Error #61

New to Altair Hyperworks and trying to run a structural analysis of a pressure vessel subjected to internal pressure and symmetrical about 3 principal planes. I get the following error.

*** ERROR # 61 ***
No grids found in the input data.

Could anyone guide me in this regard?

Hello,

I assume you are using Optistruct as a solver. Some grids must be missing in the input deck. Please recheck your .fem file that everything is defined properly

How do I check the grids definition in the .fem file?

solon

Please verify that all grid points referenced by elements, loads, and boundary conditions actually exist in the deck file and are properly defined in the bulk data section. You may also share your model for review.

I have shared the model here

solon

The fem file you attached has no elements or grid points defined.

I exported the file again from HyperMesh, it is working properly on my end.

dummy-adjusted.fem
