Does anybody know how to compute Oscillatory shear index using OpenFOAM/ParaView ?

I think it can be done using Python programmable filter, but I don't know how to iterate over the time steps...

fatal error

When I tried to energy minimization my system, I got fatal error as below. Fatal error: Atomtype opls_116 not found Although I've already added this line: ; include water #include "oplsaa.ff/spc.itp" to [molecultype] directive in my topology.

Resistor definition in Piezoelectric bimorph with ANSYS workbench

Hello, good day! I am trying to simulate similar bimorph piezoelectric harvester with below commands. However, the output power doesn't change with resistor value. Please help to find the reason. ET,10,CIRCU94,0 !SET UP RESISTOR R,1,100000 !RESISTANCE VALUE TYPE,10 !SET ELEMENT TYPE E,1,2 !CREATE RESISTOR BETWEEN NODES 1 AND 2 Thanks in advance Regards,

Arena simulation - how do i model the following model in ARENA (see description) (new to ARENA)?

Hello, I'm fairly new to ARENA and I have the following problem: I have two queues in which, in each queue, a different order type arrives (both having an arrival rate of exponential 10). Order...

Why are the velocities so high in my Boussinesq approximation Fluent simulation?

Hello, I have a mechanism where air rises due to convective flows. In this simulation, nothing is driving the air except this. I understand that the Boussinesq approximation only works for small...

What is the characteristic length to determine the Reynolds number for the scattered turbulent fluid flow?

Dear all, I just saw this example in FB on the difference between laminar flow and turbulent flow. The flow from a pipe hits the sink and scattered. The flow from the pipe is characterized as...

Did you try with Gradient of the velocity?

Sergey Sindeev

Yes, I'm on this stage now. But I don't know what to do next.

You can use calculator to multiply and obtain results,

Multiply... "what on what" ? Gradient on Normals ?

Yes, it would be very nice if you will describe every stage of WSS calculation in Paraview.

Ainal Hoque Gazi

Did you solve it in paraview?

Unfortunately, no

Iago Lessa de Oliveira

Dear Sergey Sindeev,

What simulation software are you using? Some of them have special tools to directly compute the WSS, such as OpenFOAM and Fluent, if I remember correctly. Did you try that?

Regards,

Iago

Dear Mr Oliveira, we have only MRI-measured data for the velocity field. This is not a result of CFD study...

use the normal gradient to compute the wall shear stress parallel the local wall surface, then integrate it over the wall.
