I have downloaded result for simulation of a **Stirred Tank Reactor with Multiphase Flow** simulated on **Simscale**.

Link for the project - [SimScale](https://www.simscale.com/projects/omzavare/stirred_tank_reactor_simulation_with_multiphase_flow2/)

For calculating Reynolds Number i need to first calculate **Wall Shear Stress**.  
So could you please guide me with calculating Wall Shear Stress.  
Thank You
