FEA simulations error - mesh to coarse

[robinMGH52]

Hello,

I am student mechanical engineering and at the moment I am working on several FEA simulations for a project. I do static event simulations and in the scenario, I simulate, the forces are in equilibrium. The function "remove rigid body" is activated during the simulation. Unfortunately, the simulations fail. You can find the warnings in the attachment. I think that the mesh is too coarse. The model has walls with a minimum thickness of 0.6 mm and the smallest "local mesh" mesh that is possible for this model is 2.5mm. If I activate the absolute size for the general mesh and set this to something smaller than 0.5mm crash my computer. So, does anybody know how I can solve this problem?

Hi @robinMGH52 

Could you please attach the dataset, I see errors while generating contact.

Thanks for your reply. What do you mean with "the datasheet"? In the attachment you can find pictures of the report. I can not upload the report, because of his format and unfortunately, I can not change the format.

Datasheet = dataset

Hi @robinMGH52 ,

Sorry for using technical term.

I mean your file.
File>Export your *.f3d/*.f3z file to your local drive and then attach it here to a reply.

Hi @dsouzasujay 

Thanks for the help. However, I already managed to solve the problem.

Kind regards,

Agree with @sutherland- 
Please share how you were able to fix the error, other users will get help when they get struck with same error.

The model was solved after I changed some mesh settings. The main change was the element order from parabolic to linear
