Maybe you are the right man to ask. I know the GSNDO calculates the heat of the reentry.

What about Aerodynamic forces?
Is there way to calculate the stress on a craft as it accelerates in the atmosphere? I'm not looking
at very accurate figures, just an aproximation.
Let's say we choose a max speed of 200km/s@20km(8.2kPa). What speed will give the same
stress at 10km or 40km?
