&lt;p&gt;I am using the Physical Modeller of STAAD Pro Connect Edition V22 Update 12.&lt;/p&gt;
&lt;p&gt;I have a wall that is shaped as follows. It is thicker on 1 part than the other.&lt;/p&gt;
&lt;p&gt;&lt;img style="height:58px;max-height:58px;max-width:403px;" height="58" src="/resized-image/__size/806x116/__key/communityserver-discussions-components-files/5932/pastedimage1689865334887v1.png" width="402" alt=" " /&gt;&lt;/p&gt;
&lt;p&gt;I have modeled the different thicknesses of the wall as 2 separate surfaces at the centreline of each thickness, as follows:&lt;/p&gt;
&lt;p&gt;&lt;img style="max-height:240px;max-width:320px;" src="/resized-image/__size/640x480/__key/communityserver-discussions-components-files/5932/pastedimage1689865574003v2.png" alt=" " /&gt;&lt;/p&gt;
&lt;p&gt;When the model is viewed in 3d, this means the backs of the walls line up correctly.&lt;/p&gt;
&lt;p&gt;&lt;img style="max-height:240px;max-width:320px;" src="/resized-image/__size/640x480/__key/communityserver-discussions-components-files/5932/pastedimage1689865634290v3.png" alt=" " /&gt;&lt;/p&gt;
&lt;p&gt;At the moment I have defined control/dependent relationships between the 2 surfaces every 0.5m (this is the mesh size I am using):&lt;/p&gt;
&lt;p&gt;&lt;img style="max-height:240px;max-width:320px;" src="/resized-image/__size/640x480/__key/communityserver-discussions-components-files/5932/pastedimage1689865962296v4.png" alt=" " /&gt;&lt;/p&gt;
&lt;p&gt;To ensure that the 2 surfaces are connected and forces are transferred correctly, I just want to confirm the right approach to take in this particular scenario. Would it be better to define Control/Dependent relationships between the 2 surfaces every 0.5m or would it be better to define rigid links using dummy members with a high stiffness? Or would it make no difference?&lt;/p&gt;
&lt;p&gt;Thank-You&lt;/p&gt;

&lt;p&gt;I have created a macro to extract bending, shear, and axial forces from STAAD.&lt;/p&gt;
&lt;p&gt;The forces are correct, but I am having an issue with the &amp;quot;Location of Max Axial Force&amp;quot; outputs.&lt;/p&gt;
&lt;p&gt;Please see attached screenshots. The macro is reporting that the location of the maximum axial force is 1m.&lt;/p&gt;
&lt;p&gt;But in STAAD, the location of maximum axial force is 2m. (I am using STAAD Pro Connect V22 Update 12)&lt;/p&gt;
&lt;p&gt;&lt;img style="max-height:240px;max-width:320px;" alt=" " src="/resized-image/__size/640x480/__key/communityserver-discussions-components-files/5932/pastedimage1688985695393v1.png" /&gt;&lt;/p&gt;

&lt;p&gt;The model and Excel documents are attached.&lt;/p&gt;

&lt;p&gt;I am getting 2 warnings. Both are about instability in a joint in the My direction. The joints are highlighted in red in the following image.&lt;/p&gt;
&lt;p&gt;&lt;img style="max-height:240px;max-width:320px;" src="/resized-image/__size/640x480/__key/communityserver-discussions-components-files/5932/pastedimage1686651723721v2.png" alt=" " /&gt;&lt;/p&gt;
&lt;p&gt;The joints highlighted are in the middle of the slabs. I have pinned the slab edges.&lt;/p&gt;
&lt;p&gt;Why are these being reported as instabilities?&lt;/p&gt;
&lt;p&gt;Thanks&lt;/p&gt;

&lt;p&gt;I have created a model in the physical modeller (attached).&lt;/p&gt;
&lt;p&gt;I have defined all bracing members as trusses.&lt;/p&gt;
&lt;p&gt;I am getting errors in the cross-bracing when I run the analysis. It says &amp;quot;Zero Stiffness in Direction...&amp;quot;&lt;/p&gt;
&lt;p&gt;What is the best way to model these cross-bracing members to avoid this error?&lt;/p&gt;

&lt;p&gt;I have created a model in the Physical Modeller. The structure I am designing has 50x8mm flat steel bars. As this type of section is not available in the section database, I have added a generic section to my model. I have around 10 of these sections, highlighted in the screenshot below:&lt;/p&gt;
&lt;p&gt;&lt;img style="max-height:240px;max-width:320px;" src="/resized-image/__size/640x480/__key/communityserver-discussions-components-files/5932/pastedimage1683110018702v2.png" alt=" " /&gt;&lt;/p&gt;
&lt;p&gt;The section I have defined is shown in this screenshot:&lt;/p&gt;
&lt;p&gt;&lt;img style="max-height:240px;max-width:320px;" src="/resized-image/__size/640x480/__key/communityserver-discussions-components-files/5932/pastedimage1683110062978v3.png" alt=" " /&gt;&lt;/p&gt;
&lt;p&gt;When I run the design, STAAD is not designing the sections as the Actual Ratio is coming out to Infinity.&lt;/p&gt;
&lt;p&gt;&lt;img style="max-height:240px;max-width:320px;" src="/resized-image/__size/640x480/__key/communityserver-discussions-components-files/5932/pastedimage1683110123329v4.png" alt=" " /&gt;&lt;/p&gt;
&lt;p&gt;What is the best way to amend my model to get STAAD to design these sections? (I am designing to Eurocodes)&lt;/p&gt;
&lt;p&gt;Model attached&lt;/p&gt;
&lt;p&gt;Thank-You for your help,&lt;/p&gt;

&lt;p&gt;&lt;/p&gt;
&lt;p&gt;I have a beam on top of a beam, see highlighted beams in the image below:&lt;/p&gt;
&lt;p&gt;&lt;img style="max-height:240px;max-width:320px;" alt=" " src="/resized-image/__size/640x480/__key/communityserver-discussions-components-files/5932/pastedimage1683120701789v1.png" /&gt;&lt;/p&gt;
&lt;p&gt;I am using a Control/Dependant relationship to connect them as they are at different levels:&lt;/p&gt;
&lt;p&gt;&lt;img style="max-height:240px;max-width:320px;" alt=" " src="/resized-image/__size/640x480/__key/communityserver-discussions-components-files/5932/pastedimage1683120817966v2.png" /&gt;&lt;/p&gt;
&lt;p&gt;I currently have Node 102 (the top beam) as the control.&lt;/p&gt;
&lt;p&gt;This is an existing structure. Both beams are channel sections that are bolted together. It is a pin connection.&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;To model this correctly and avoid errors, which degrees of freedom should I fix?&amp;nbsp;&lt;/p&gt;
&lt;p&gt;I have Hinged both ends of the top beam, so should I just fix all 6 DOF. Will STAAD recognise that the beam is hinged and then only transfer the relevant forces if I fix all 6 DOF?&lt;/p&gt;
&lt;p&gt;Or should I fix Fy, Fx, Fz &amp;amp; Mx and release My &amp;amp; Mz - just like a hinged end of a beam?&lt;/p&gt;

&lt;p&gt;I have created a simply supported steel beam in the Physical Modeller (Connect Edition&amp;nbsp;22.11.00.156). I am designing the beam to the UK National Annex of Eurocode 3.&lt;/p&gt;
&lt;p&gt;I have attached 2 different models, the first is a simply supported steel beam with the material&amp;nbsp;specified as S275. On the second model, I have specified the material as S355.&lt;/p&gt;
&lt;p&gt;&lt;span&gt;When I change the material from S275 to S355, the Design Capacities do not change. See the screenshots below:&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;&lt;img style="max-height:240px;max-width:320px;" src="/resized-image/__size/640x480/__key/communityserver-discussions-components-files/5932/pastedimage1682600857905v1.png" alt=" " /&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;&lt;img style="max-height:240px;max-width:320px;" src="/resized-image/__size/640x480/__key/communityserver-discussions-components-files/5932/pastedimage1682600881545v2.png" alt=" " /&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;The program seems to be defaulting to S235, even though I specified in the Physical Modeller to use S275 and S355.&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;Unless I have done something wrong, there seems to be a bug where the program does not apply the correct material even though I have specified what to use in the physical modeller.&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;Thank-You for your help,&lt;/span&gt;&lt;/p&gt;
