OK, my foolness. Just double click "Finite Element Model.1" and one can go back to the right module. Then the "Import/Export" toolbar would appear.

I followed the steps described in thread560-320686. However, I couldn't find the "Import/Export" toolbar in "Advanced Meshing Tools" module. I went to View->Toolbars and searched "Import/Export", but it is not there. Could anyone tell me how to make it appear? Or I am using a wrong module? Thank...

I looked up the chapters introducing Multiphase Models of tutorial . In the chapter "Tutorial Guide/Using the Mixture and Eulerian Multiphase Models," Mixture Model and Eulerian model are using velocity inlet and outflow boundaries for steady simulation. However, in the chapter " User's...

Hi~ I built a model using Eulerian two-phase model with Population Balance Model in Fluent. A cylindrical tank with the height 2 m and the diameter 1 m contained 80% water inside. The pressure outlet was at top. Only air is allowed to flow back and no bin using PBM discrete method could flow...

What software do you use?

Hi~ I built up s model using Finite rate/Eddy dissipation with surface reaction. The surface reaction is calculated using Arrhenius rate. The option for Mixing rate is blocked an turned grey in setup window. I found that "Rate of Reaction" is zero, "Kinetic Rate of Reaction" is a non-zero...

Hi~ I got another problem with finite rate/eddy dissipation model using surface reaction. The surface reaction was activated by 1.Model→Species transport→check "Wall surface" 2.Assign material in mixture to "Site species" 3.Material→Mixture→Create "Wall Surface Reaction" and "Mechanism"...

OK, I found a solution. just like this: A=double(A) It seems the glitch is the format.

Hi~ When I try to solve some equations, I found the solution was all fractions. check the value of each vector, I found where the situation start. The codes are like this: A12=[5.5,398,455] syms a b c A=[a,b,c] AA12=A12-A and the output were: A12 = 5.5000 398.0000 455.0000 A = [ a...

the main program of MATLAB is too old or some feature is closed?

I added a formula on a point in Formula Editor as attached picture, but I can't require the curvature value. Would you please kindly tell me how to do? Thank you! http://files.engineering.com/getfile.aspx?folder=a38fa99c-e5b7-4a10-bcf5-5ec3a7027012&file=???.png

The curvature or curvature radius of any point on a surface can be shown in CATIA using "On the fly" in "Surface Curvature Analysis," and I can't executed this function on a certain position. What I can do is to move my pointer and see the value on the CATIA window, but this would not show a...

thread560-320686 Hi~ I export a .dat file from a surface. I thought that maybe they are coordinate of nodes. However, I don't know how to read it. Can anyone kindly help? Thank you! The data in the file was like this: $.. $---------------------------------------- $.. $.. BULK DATA...

Hi~ Can I create cloud point in CATIA? I know that I can create points by my own using a lot of parallel planes and lines. Is there a function in CATIA for this operation? Thank you.

Hi~ I am using CATIA V5R21. I am trying to analyze the curvature and curvature radius of a surface in CATIA. However I found I can't export the curvature along any curve or on a certain point along a certain diraction on the surface. I thought maybe it is possible to export the surface to MATLAB...
