Thank you very much. I'll give it a try tomorrow

hi Ceyhan Sorry, I did not find a place in A2 where I can set up SCDM software scripts. Thank you for your reminder. I have set "Use SpaceClaim color tones when importing" in SCDM. Do you mean that the color of the bottom, side, and top surfaces of C inherits from（is the same as） B1, B2, B3? The fan wall inside C inherit from（is the same as） A1? thanks graychen

hi Ceyhan Thank you for your answer The first problem: I solved the problem of changing the unit to mm in CAESES. The third question: I achieved the goal of closing the blade tip through a feature of a propeller in the tutorial. Second question: I did not see a place in the properties of A-3 where I can set the script path (as shown in the figure below), so I don't know how to load the recorded script into the program. Do you know where to set it? The current solution is to create an external computing domain in CAESES as recommended by you. But I encountered another problem with this method, which is described below. I created a fan A in CAESES, and the color of the entire brep is A1。it is necessary to create a cylindrical dynamic domain because of CFD. So we created a cylindrical Brep B with the colors B1, B2, and B3 for the bottom, side, and top surfaces of the cylinder. B wraps around A. In CAESES, Boolean operations are used to cut off A in B to obtain Brep C, which is the external computational domain required for CFD. However, in this case, BrepC is an integral BREP and can only be set with one color for the whole. How to set the different colors of the inlet, outlet, side,and fan wall regions separately? thanks

Sorry to bother you...

I have three questions about CAESES、 workbench and propeller feature。 1、Import an existing STEP geometry in CAESES with units in meters and dimensions is 0.0046m=4.6mm, but when I import FSC into the workbench and opening it through SCDM, the size has changed to 0.0046mm. The size has been reduced by a thousand times. How to correct it? 2、After importing geometry A into CAESES on the workbench platform, it is necessary to performExternal flow CFD analysis on A. Therefore, an external computational domain was created using SCDM in the A-3 module to form B. when the parameters of CAESES were modified, and the geometry in the A-3 module became C, but SCDM did not automatically create an external computational domain for it. So my question is, if in the optimization process, it is necessary to automatically create external computational domains for parameterized geometry, what should be done? 3、A propeller was created using CAESES' propeller feature. Since CFD calculation requires a closed geometry。 how can the tail and tip of the blade be closed for CFD calculation?
