Same case (OF-CUDA) crashes in the first machine while runs on my laptop
 

Hello Foamers,

Last month i start to work with a solver of the OpenFoam that uses the cuda environment in order to simulate the break up of the bubbles.

The code run smoothly on my laptop and i am very happy about the results (I7-gtx1650).

I try to compile the same code in a machine that has a Ryzen3950X processor and nvidia gpu and when i try to solve the same case as in my laptop and the following errors appear.

I think that is a memory problem. What is causing the difference between the two machines ?
