Stuck in UEqn.A()

October 30, 2017, 17:26

Dear FOAMers,

my solver gets stuck executing following expression in the pressure equation:
rAU = 1.0 / UEqn.A();

It happens in parallel mode. I already checked the diagonal elements of the UEqn-matrix, but couldn't find any anomalities. The solver does not crash, it just stops... Any ideas?

Regards,
M

Hi,
do you have more info?
Which OpenFOAM version?
does it happen only with one particular decomposition?
Is there anything else strange?
Does your solver manipulates somehow with the matrix?
