Hi!

I am facing an issue when I a try to inverse a volTensorField. For example :

Code:
volTensorField TM1 = blah blah blah;
volTensorField invTM1 = inv(TM1);
compile but leads to an error while it runs..

Do you have any idea to overcome this problem ?

Best regards,
Cyp

Hi Cyp,

can you try the following:

Code:
tensorField TM1internal = TM1.internalField();
tensorField invTM1internal = inv(TM1internal);
Than you can copy it back to the internalField of a volTensorField.
Be aware: A lot of the methods are not available for complete GeometricFields (like your volTensorField) since they could mess with the boundary conditions.

Best

Kathrin

Thank for your answer !

In fact the main problem came from a division by zero. Nevertheless, the results are not the one I expected (my other topic..)
