Hello to everyone reading this thread,

I try to perform a DNS simulation of an incompressible flow by using the pimple algorithm in OpenFOAM. As the resolution of the computational mesh is too high to save all the data at all the points, we decided to save only the data in a restricted area of the domain by using the probe function (writen in the controlDict file). Everything seems to work perfectly except that the use of the probe function seems to slow down the computation and limit the scalability of the computation, even with one probe. It seems that the probe function is called and search the probe locations in the domain at every time step even if the data are saved in the right post-processing files every two time steps.

Does anyone know how to avoid the call of the probe function at every time step but only for the times when it is necessary to save the data ?

Thank you in advance.
