  • Hello,

    I have notices 2 issues in your file.

    1. For the Time load (seismic case in your file) you  have not defined any seismic mass. So, the program is throwing that error.

    As a solution please define some loads in 3 directions under load case 5 before ground motion data. As a reference you may refer example number 22.

    2. The materials you have used is having zero density and no Poisson's ratio value. Plaese review and put some value for the program to work as intended.

      

    Hope this helps!

    Thanks & Regards,
