ERROR # 1000 HELP!!!!!!
Altair EmployeeI want to analyze the stress and strain of helical gear pairs.
But I have already set the properties of all the components.
Does anyone have an idea? Help me.Please!

Hi @siyemusu
The error is coming from RADPRM control card which is not required for a linear static analysis.
I can see you are trying to simulate gear mechanism with contacts. Please use NLSTAT with LGDISP instead of Linear static analysis.

Hi @ Prakash Pagadala ,(I don't know how to @ others...)
Should I delete the RADPRM control card like this?

And where to set NLSTAT? I'm new to this software.

Yes, please delete Randprm and try again.

Hi,
The element quality is too bad and the violates basic qualities. You may have to remesh the components,

OMG! Is there any other ways to ignore this problems and get the stress nephogram?
I'm sorry the time is running out.

I am sorry about that, but I need some time to investigate.

Hi @siyemusu
Use ELEMQUAL>> TETRA>> TWIST ANGLE>> with an upper bound of 100 and check if that helps.

I have remeshed the components and succeed to run the results.
Thank you for your help.

Thank you for the update. Remeshing is a good option over tweqking the element quality values as it may produce weired results

I met a problem.I used 'solid edit' to spit the gears and then meshed. Now I want to merge the elements as a whole.How to merge?

Hi,
If the elements are in different components, you can use Organize panel(shift+f11) to move the element to a single component,
Also, make sure the elements are connected nodally.

The elements are not connected nodally.I want to use interfaces. The element type should be stick or freeze?

Depends, Freeze will make sure that relative displacement between the nodes is zero,
Stick is a situation where nodes/elements from both components come in contact and stick to each other after that.
