Error #369

Hello Forum, 

 

Im from the Hawks Racing Team in Hamburg and i have some problems with a special error in Optistruct.

I created my Model on my laptop and switched to a stationary computer to do the simulations for our racecar.

On both Stations a check run was done and no errors occured.

As i started the analysis/optimisation on my laptop everything was fine but it took to much time..

When i start the same optimisation on my stationary maschine i get the error #369.

See Picture 1 

My Inertia Relief Constraints are able to see on picture 2 

I checked so far all Loadsteps 

- changed the position of the inertia relief constraints 

-did a element cleanup  

-did a new definition of plys.. 

-I deleted the Element with the id 1095447

 

 

and the problem is that for that error there is no solution on the internet. 

Maybe this forum can help me.

I copied the whole Modell folder from my laptop to the stationary maschine 

 

The problems has to be in the settings of windows or hypermesh 

 

Has anybody a idea ?

 

Greetings

    Maybe some more input:

     

    ITERATION   0
     *** ERROR # 369 ***
     Auto-spc dof has non-zero mass/inertia.
     Degree of freedom  = 4.
     Grid Point ID      = 1095447.
     Mass/Inertia value = 2.0759e-006.
     When this happens, inertia relief force calculation is incorrect.
     The corresponding static solution is erroneous with
     nonzero SPC forces at the SUPORT dofs.
     This error occurs in module 'lstatdrv'.
