Has anybody validated that approach? I'm not convinced it's accurate since you would be using a distance weighted interpolation method to interpolate in time.

Use a 1D interpolation function and use the function for your boundary condition value.

Please find the attached document for your perusal. Please comment on the following 1. Is my profile boundary correct? 2. I applied the following settings in the boundary details>mass and momentum>option>total pressure (stable)>Relative pressure>inlet.pressure(t) Thank you Regards Shashwat |
