Reply To: Error running Bolted Pressure Vessel model

Check the nunber of nodes and elements under the statistics in the details of the mesh object in the Outline.

Student problem size limitation are discussed here:

/forum/forums/topic/limitations-to-student-license/

"In a Structural model you add the number of elements to the number of nodes in the mesh, the sum should be less than 32k.  That is more strictly enforced and sometimes, the solver goes off and creates a lot of contact elements and refuses to run because the additional elements created push the model over the 32k limit even though the mesh you see in Mechanical was < 32k."

I can't confirm exactly the 32k limit discussed in that forum post except when using SPEOS. The structural limit looks to be 128K nodes/elements:
