Internal Error - PH02246melem.ff

Altair Forum User

Hello,

solving a hypermesh model in HyperXtrude leads to an internal error. The only additional information is 'PH02246melem.ff'.

It happens in the second time iteration, log says:

***** Time Step: 2 of 35, Step Size = 0.25 sec *****

***** Nonlinear Iteration Number : 9 of 25 *****

TEMPERATURE CALCULATION STEP

----------------------------

VELOCITY CALCULATION STEP

-------------------------

**** SOLVER ERROR STOP ****

Any idea, where to look, to get that working again?

Thanks,

J.

I had a similar error <ph00635assm-dri>

I found that that there were zero diagonals in the matrix...

I was able to find the most likely cause... five 3D mesh elemnts got deleted while i was fixing the boundary conditions... So, may be u need to re-examine ur mesh.. thats my guess (I m a newbie too!!)

Zero diagonals resulted, probably, because element connectivity in the matrix could not be established due to the missing elements.. agian a wild guess!!
