Probable bugs and suggestions in RM Bridge

The version is 08.11.18.01 Advanced

Bugs

1.  In Modeler -> Segments, I create a Spring-0 at point 7,  the spring number is 8001. Then I want to copy the spring to other points using "Copy spring-0" function and input the number as below

I would expect to see spring 8002 at point 11, spring 8003 at point 15, and finally spring 8023 at point 95.

But after I press "OK" button, RM Bridge gives me spring 8002 at point 11, for which I expect, and 8006 at point 15 and finally spring 8086 at point 95, for which I don't expect. It looks like RM Bridge uses step=1 only for the first point and then magically uses step=4 for the following points.

more screenshots shows spring at points 11, 15 and 95.

  • 2. Both main girder and cross member have composite sections.

    In the Analyzer -> Stage -> Activation, when I select elements using "Assembly",

    for main girder, it allow me to select different parts, as below

    But for the cross member, it doesn't allow me to do so, it only show "All"

    although the cross member has composite section defined as below. If I select 'All", only the elements of part 1 will be activated.

  • Suggestion

    1. When I use copy spring function as I mentioned in the Bug 1, if I made mistakes and input wrong parameters
        RM Bridge will creates springs at unwanted points and it's time consuming to go to every point and delete these springs one by one.
        Is it possible to improve "delete spring"?


    2. Is it possible to allow assigning spring to groups, and shown them in the Analyzer -> Stage -> Assembly?

    3. The name of load set or load case are limited to about 14 characters, can this limit be removed?

  • Hi,

    regarding Point 1, I checked the code and it seems to be intentionally like this. The "philosophy" is that it is easier then to create additional springs at the segment points which are skipped by the copy action and give them numbers with the same relation to the segment point.
    This dialog been started with some basic input and default behavior and not yet fully developed. We are extending the possibilities to make it easy to input a sequence you expected as well. Further the need of having a better delete/undo function is obvious as for wrong input we get a vast amount of unneeded springs which can only be removed one by one, now.

    For Point 2, this cannot be solved easily. We cannot auto-generate assemblies for any combination of elements. What was missing and is fixed now, is that in the case cross members or cables are composite not all parts were included in the generated assemblies. But this does not include now, that the parts can be addressed separately.

    Point 3: Names are generally limited to 16 characters in RM. This has historical reasons and will not change in short term.
