    How to export mesh in "Advanced Meshing Tools" module?

    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.

    How to export mesh in "Advanced Meshing Tools" module?

    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...

    Multiphase Eulerian Model with outflow boundary?

    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...

    How the bubbles dissipate using Population Balance Model?

    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...

    How to calculate the production rate of some surface reaction in FLUENT?

    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...

    finite rate/eddy dissipation model with surface reaction?

    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"...

    why the symbolic vector minus a scalar vector produce a vector with fraction?

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

    why the symbolic vector minus a scalar vector produce a vector with fraction?

    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...

    How to import CATIA file to MATLAB for analysis of curvature radius?

    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

    How to import CATIA file to MATLAB for analysis of curvature radius?

    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...

    How to create cloud points of a model built in CATIA?

    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.

    How to import CATIA file to MATLAB for analysis of curvature radius?

    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...

    How to get mass fraction of a multi-component particle injected into a tank using DPM+UDF

    One particle composed of one evaporating and one inert material was injected into a tank. The mass fractions of original evaporating and inert material were 0.8 and 0.2, respectively. They could be set up through Define→Injection→Component. How to get evaporating mass fraction remained in...

    How to get the mass flow of some species out of the domain in Non-premixed model(PDF model)?

    ...ANSYS14. T try to find the mass flow rate of a certain species out of the surface in a domain. Originally, the mass flow can be written as "F_FLUX*F_YI" However, I found it is not allowed to use F_YI when Non-premixed model was applied, that is written in the manual "3.2.3.6.1. Species...

    Error "epsilon too small" when using DPM

    Hi~ I am using ANSYS14 to simulate drop particle in a cylinder by DPM(Discrete Phase Model) and LES model(Large-Eddy-Simulation model). The error "epsilon too small" appeared after 1.82 seconds, that is Flow time = 0.183s, time step = 183, which is as follows: " DPM Iteration .... Internal...

    Curvature definition in Solidworks

    Hi~ I am using Solidworks and CATIA. CATIA provides Gaussian curvature and mean curvature for surface analysis. However, I can not find out which surface curvature is provided in Solidworks. Is it Gaussian curvature, mean curvature, minimum curvature, or other definition? In the HELP documents...
