Hi everyone,

I have been trying to compile a new solver phaseChangeHeatFoam with dynamic meshing capabilities. Which I call as phaseChangeHeatDyMFoam.

Now the problem is i have given end time as 20 sec and deltaT of 1e-5. still the code ends after solving for the first iteration. Its not running in loop. What can be the possible solution?

HTML Code:
Create time

Create mesh for time = 0

Selecting dynamicFvMesh dynamicRefineFvMesh
Reading field p_rgh

Reading field T

Reading field alpha1

Reading field U

Reading/calculating face flux field phi

Creating phaseChangeTwoPhaseMixture

Selecting phaseChange model Hardt
Selecting incompressible transport model Newtonian
Selecting incompressible transport model Newtonian
Selecting turbulence model type laminar

Reading g

Reading hRef
Calculating field g.h

No finite volume options present

Creating field kinetic energy K

Hi,

You should give more information, but it is very likely that you have modified the main file of the solver (i guess it's called phaseChangeHeatDyMFoam.C) in a way that you commented or deleted the time loop that makes the solver go to the beginning.

Could u post that file over here? Or at least check if you have modified the main time loop

Regards,
Alex

Alejandro Valeije,

Thanks. You were right. I misplaced bracket in the time loop. I corrected it. This solved the problem.
