Dear Jonas,

Thank you very much for your detailed explanation and support.

I am impressed by how many different structural analyses can be performed in GeoDict. The visualization options and analysis capabilities are very helpful for my research.

In addition to importing catalyst layer structures from CT images, I am also interested in creating catalyst layer models directly within GeoDict.

Could you please advise me on how to incorporate actual catalyst data into GeoDict when generating a structure? For example, if I have information about the catalyst particles such as particle size distribution, shape, or loading, how can these data be implemented in GeoDict?

I would also like to know whether it is possible to connect individual particles together and represent them as a fiber-like structure within GeoDict. If so, which module or workflow would be most suitable for this purpose?

Thank you very much for your time and assistance.

Best regards,

Hello,

Thank you very much for your kind and detailed answer to my previous question.
I was able to solve the visualization problem successfully.

I have another question regarding the structural analysis capabilities of GeoDict.

My research focuses on understanding the structure of fuel cell catalyst layers.
I imported CT images of an actual fibrous catalyst layer into GeoDict and reconstructed the 3D structure.

I would like to analyze the reconstructed catalyst layer in GeoDict and evaluate structural properties related to mass transport and morphology, such as:

diffusivity,
tortuosity,
bottleneck diameter,
pore size distribution,
and other structural parameters.

My questions are:

What kinds of structural or transport properties can be evaluated from reconstructed CT structures in GeoDict?
How many different material properties can GeoDict calculate for this type of porous structure?
How accurate are these calculated properties compared with experimental measurements or real structures?

I am especially interested in evaluating transport characteristics inside fibrous catalyst layers for fuel cell applications.

Thank you very much for your support.

Hello,

I imported CT TIFF images of a fibrous catalyst layer into GeoDict and successfully reconstructed the structure.

However, I have a problem with the visualization.
The pore space is displayed as a white phase, so the internal fiber structure cannot be seen clearly.

I would like to know if it is possible to:

・make the pore space transparent,
・hide the pore phase completely,
・or directly visualize only the fiber structure inside the reconstructed model.

Could you please tell me how to change these visualization settings in GeoDict?

I attached an image showing the current problem.

Thank you very much for your help.
