CFD Tips for Running on Rescale

Running computational fluid dynamics (CFD) problems on Rescale is akin to executing them on a local environment but with some additional considerations for efficiency and error management. Ensuring that the job runs successfully on a local setup before submitting to Rescale can prevent costly mistakes. The platform's Live Tailing feature allows users to monitor files in real-time, providing insights into errors or progress, while plotting residuals as image files can offer further analysis. Intervention during computation, such as adjusting parameters via SSH, can save runs from bad initial choices. Managing the large number of small result files effectively, by writing in binary or archiving them, can mitigate data transfer times. Rescale also offers remote desktop capabilities and the use of ParaView for viewing results without the need for downloading, enhancing convenience for users with limited bandwidth.
