Does anyone know of a method for recovering the hydraulic radius distribution from a CT image of a pore geometry?

I have a segmented CT image of a pore geometry. I can compute the skeleton on the geometry no problem and get an estimated hydraulic radius at each location along the skeleton by interpolating the...

Can I perform sparse matrix operations in Matlab with single precision?

I wrote a very nice Matlab code that solves Laplace's equation on a 3-D complicated geometry. The solver is implicit, so my systems of equations is reduced to a matrix equation. I use a...

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,

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...

Steffen Berg

there is a commercial code available in GeoDICT

http://www.geodict.de/

Kevin J. Miller

Thanks Steffen. Though freeware is preferable, GeoDict is a promising lead. Do you know if they offer a free trial so that I may evaluate their software?

Sometimes, COMSOL could provide a short term license when you attend their public seminar or webinar.

I have access to COMSOL, can it really handle multi-scale fluid flow?

Dear Kevin,

Now can you share you code solving Darcy-Stokes equation?
