Hello everyone,
I have a question about flow-3d. I ran a model, and when the simulation stopped, I received the following error message. Even after modifying multiplier for dynamically adjusted convergence criterion and Maximum number ofiterations before time step is reduced, there was no improvement in the result. Initial time step is 0.001s. Minimun time step is 1e-09. Pressure solver is GMRES.
Mesh aspect ratio not exceeding 1:3. I'm unsure where the issue is occurring and am seeking assistance.
Best regards
pressure iteration did not converge in itmax= 100 iterations
at time= 1.62463E+03 cycle= 55 iter= 100 nocon= 0
epsi= 3.548E+04 maximum residual= 4.091E+04 at i= 202 j= 27 k= 3 block= 1
*** time-step size < dtmin ***
delt = 7.81805E-10 dtmin = 1.00000E-09
