Static Structural Tool in ANSYS, General Error

[Burner21]

Hello everyone

Just a quick question, hopefully someone could shed some light upon what I'm doing wrong here?

I'm using ANSYS Workbench to apply a force to what is effectively a cantilever beam, fixed at one end, with a load applied at the other. To be more specific it is a spring strut of a light aircrafts landing gear, where the load is a calculated force at touchdown of landing, so the load bearing end has a wheel assembly attached that I created using Siemens NX.

I've defined the materials of each section, produced a mesh and applied the load force and fixed support at either end, but when I run the solution I get the following error message:

"An error occurred inside the SOLVER module: general error."

Does anybody have any idea what could be causing this? Appreciate any help you can give. Thank you.

Hey Burner

I was having the same problem, but i just worked out what was causing it for me.

I think I am using an education license, which limits the number of nodes you can have in a model. If you exceed it then it gives you this error. I reduced the size of my model and reduced the number of nodes I was using and the problem went away.

The model I am working with at the moment has just under 125000 nodes. A model twice the size didn't run, so id guess the cut off could be between 125000 and 250000 - although I'm not sure.

Try reducing your model size.

Hi there,

I'm not an expert in ANSYS Workbench, but from what you've described, it sounds like you've done everything correctly. It's possible that there could be an issue with the mesh or the material properties you've defined. Have you tried checking for any errors or warnings in the pre-processing stage? Also, have you tried running the solution with different mesh settings or material properties to see if that makes a difference?

Another possibility could be that the load force you've applied is too high for the beam to handle, causing the solver to fail. Have you tried reducing the load and seeing if the solution runs successfully?

If none of these solutions work, it might be helpful to reach out to the ANSYS support team for further assistance. They might be able to provide more specific guidance on what could be causing the general error. Hope this helps!
