pressure specified in UCSN3D.dat is zero (will not work with this value)-you must specify here the static pressure |
Hi. I tried doing what you said and it is having the same issue. I even tried using a pressure inlet boundary condition but it is having the same effect. Can you tell me what I am doing wrong? |
the pressure specified at the UCNS3D.DAT is the static pressure. |
I have a simple liquid injection in a quiescent environment problem. Is it advisable to write a custom initial conditions profile or can the default initial condition profile handle this? |
you should create a custom initial conditions profile |
Hi. I am running a multispecies problem but the solution ends within 3 seconds and the first time step in history.txt is extremely large. This is happening only for the multispecies problems. I tried refining my mesh and reducing my CFL number but the result is the same. I have attached my UCNS3D.DAT, MULTISPECIES.DAT, and history.txt files. Please let me know if I am setting up the problem incorrectly.
history.txt
MULTISPECIES.txt
