Default Post Processing Partial Result files

Hi, I am doing a transient simulation. Inorder to reduce the size of the result files I choose only relevant varibles to be output in the res file. Although it reduces the file size, it also causes problems in POST. I am not able to calculate mass flow and torque accurately. I have learnt that for partial result files, the integration point flows are not written, hence this cud be the problem. Is there a way to overcome this or is there another method to reduce the size of the output files??

Thanks, Sans

You need to include all the variables that the code needs to calculate mass flow and torque e.g. density, velocity, pressure, surface shear stress.

Yes all of those variables have been included.

Sans,

there is an (undocumented) Expert Parameter you can set to include the ip mass flow in the partial results files:

mfloip to trn files = t

This will give you accurate mass flow calculations in Post at the expense of larger file sizes.

Don't forget to set "output boundary flows = t" as well so that you can compute accurate forces.

rezendervp is on a distinguished road
The tip from Johnson is correct and will fix the calculations, but i think you still want a small file size, try also to use one available compression options , you will have a compromise among precision and HD space.
