Diffusion analysis ABAQUS CAE tutorial | Diffusivity and Fick's Law

As you mention at 3:10 , could you make pressure and temperature driven hydrogen diffusion analysis video or give a small guidance on this topic ? Any kind of help is appreciated. Thanks

[@prz90]

It was very helpful. could you make another content on 3D diffusion analysis? I am working on composites and need an education content to guide me in the simulation process

[@NotRealEngineering]

I will try my best

[@mohammadrezaparsaeian5448]

@@NotRealEngineering me too I would appreciate it if you could do that

hi, thanks for this toturial, could you make pressure and temperature driven hydrogen diffusion analysis video or give a small guidance on this topic ? Thanks in advance

[@shivtil9037]

please make temperature drive and pressure driven diffusion analysis

[@zeinabmohammadi1379]

Thanke you for your great toturial. I was wondering If we can use the mass diffusion analysis results as a material input for another for example static general step. I wanted to know is it possible? thanks in advance for your answering

Hello, how can I define optimum timestep for my permeation problem?

[@RezaFaramarzi-iy5gr]

It was very helpful. how can we make it figure out diffusibility Coefficient rather than defining it ourselves?

Could you provide detail video on moisture diffusion on polymer?

[@learneasyonline]

I have a microstructure where a fluid diffuses from position A (high pressure, high viscosity and high density) to position B (low pressure, low viscosity and low density). Can we treat this as a diffusion problem and solve it in Abaqus? Maybe we can do something using usdfld, but I am unsure. It would be great if you could make a video on it. I really appreciate any help you can provide.

Can this be extended for a multispecies diffusion? say we have different species in a compound.

[@invisibleman2059]

Is it possible to do this in Ansys?

[@saroj4736]

have you find it

[@invisibleman2059]

@@saroj4736 Yes, with a code in APDL

[@toren101]

Thanks, 1.Can you do 3D diffusion problem? 2.Can the diffusibility be dependent on fiber direction in a composite material?

[@prz90]

Hi, I just started to do FEM on the diffusion in sandwich panels. it seems that you are working in the same area. I would be happy if you could share your knowledge!

[@user-qq9sp6xw7z]

Do you have knowledge of how to perform 3d moisture diffusion analysis

[@saroj4736]

can we do the same in ansys please let me know
