Error 4820 Fixed BC in SPC not supported for linear static analysis

Shubham Jain

I’m getting the error #4820 (the fixed BC in SPC is not supported by linear static analysis) consistently on every model I create

My friend followed the same steps and was able to solve the model 

 

The problem I guess will be with some setting I need to change

I don’t think if I tweaked some settings before though 

 

Anyone faced this issue before ?

Hi,

Which version are you using? Can you share the model?

Hello, actually the solution is not present. Could you provide it? How did you manage the boundary conditions and loads?

Hello!

I am also getting this issue. I am trying to apply two loads onto an axle and Hypermesh doesn't seem to like it if I apply the constraints to the whole face of either end or just a point at the bottom.

 

Thanks!
