Hello, I am enclosing two photos in which they appear errors that do not allow me to perform the modal analysis. Static analysis is performed. How can i tell where are the errors? Thanks

Change solver onto Automatic then check

 

As far as I can see your model is not perfectly corrected after importing from Revit. PLease send me robot file to check.

It took me more time than I expected - too many errors (some geometrical errors not corrected by you as I had asked before).Finally I corrected model.

1. Geometry not corrected  - some columns  127 128 157 158 194 195 etc not connected to panels \ beams -> use Detailed Correct \ To plane to correct 

2. ALL bars in project are released - I guess due to Revit settings. In attached file I removed releases from columns

3. Linear releases can not be defined on free panel edges

4. Linear releases can not be defined on both sides on common edge if there is no bar  \ wall on the comon edge defined.

5. Do not use kinematic links, corect meshes either by program (local mesh generation) or manually moving nodes.

6. Walls (as far as I remember  27 274  not accurately connected with slabs)

7. Due to inaccuracies Model Generation tolerance should be set as 2mm

Thank you for your support. I remain some doubts: -If I execute the correct calculation of the model you are found free nodes, if I deletethem then reappear. Can I ignore them? -In the Revit model is graphically correct, because robots are created in all those discrepancies? thanks again

Ignore these 

Check Analitical Model in Revit with big zoom, not the graphical model.

Upload the latest version of rvt file and I will check it.

Rafal, I am attaching the file to Revit. I think that should be improved interoperability with Revit Robot. I do not think my model is very complex, yet provides these problems.

Thank you again.
