more interpolation points
 
Hi,

I am using OF-2.0.1. I am trying to validate my solver. the case is supersonic flow over a moving cylinder inside a closed domain. I have got the shock captured well and my density, mach no.. profiles are matching well wrt pattern. Not able to capture the peaks correctly.

When I looked closely into the data files, I found that there may not be enough data points close to the shock. Otherwise, the simulation matches well with actual result.

Now, what i want to know is how to specify (interpolation scheme) in sampleDict file so that i can have more data points close to the shock (shock position is known wrt cylinder).
quick reply would be very helpful

sampleDict interpolation
 
Hi Achy,

Are you interested in increasing the interpolation points inside a volume, on a plane, or surface? Are you open to increasing the mesh resolution in that area/volume? Please post your current sampleDict using the [ code] [ /code] tags (without the space) so that it is readable.

Hi,

I want to have more interpolation points on a plane capturing the shock. i realize better mesh resolution is one option but i do not want to run the case again. is there any provision in sample dict.

I have attached my sample Dict.
