From the physical modeler I created an analytical model, successfully, but nothing appeared in the Analytical Modeling view and I could not go back to the Physical Modeling view.
Hello,
Can you please upload the .std & .stdp file here? Also, please mention the version number of STAAD.Pro you are using.
For what it's worth, I was able to open the physical model in the latest version (22.02.00.26). I then successfully went to the analytical model and ran it. There was no PERFORM ANALYSIS command so I added it. It then ran with no errors.
