    Hello, 

    It seems like you have GPU acceleration turned on. The error is basically indicating that your GPU memory is not large enough to fit your computational model when the number of cells is greater than 1.2 million. 

    Thanks,

    Kalyan

    do you have any suggestions for converging problems? i sat up 750 iterations but it shows floating point exception after 250 iterations.. i have played around with the URF and i changed the pressure outlet to out flow BC because when i was using pressure outlet i got reverse flow.. the reverse flow issue solved but remaining the floating points problems.

     

    thank you for your guidance
