gradient IEEE error
 
Hi all,

I'm using CFX-4.3 for the purpose of combustion modelling. Therefor I'm solving some 'user scalar' equations. With a couple of these user scalars CFX gives a 'IEEE invalid operation' (no overflow or division by zero) as soon as the gradient of the scalars is called with the routine GRADS. What might be a cause of this and what are possible solutions?

Thanks for your patience, Bram

I think you have to call the subroutine DELWRK before you leave the subroutine. You have to call the subroutine only once with the first field, you set by SETWRK as argument. Fabian

Re: gradient IEEE error Solved
 
Hi there,

The problem is solved. Just a stupid coding error. But thanks for the reaction.

cheers, Bram
