Solution diverges on the first time step with an extremely large time step.

[sidkamat]

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 UCNS3D.txt
