    Hello there, Please open the geometry in Hypermesh with AcuSolve as a user profile and export that in ".nas" format.
  2. Hello, While exporting from hypermesh file (.hm), make sure that you are exporting only solids and there is no surface in that. You are getting error that it cannot detect any regions!

    Hi, Have you tried all the options mentioned above?? Pl send the model on edu-support@india.altair.com, I'll check whats wrong with the model.

    Also check whether you have selected User Profile as AcuSolve or not...!

    importing nastran file to AcuConsole

    Try to manage the surfaces properly. Hope you are using 14.0 version onward and export in Nastran(fluent) standard format, surely this will help.

    About command 'PURGE'

    Hello, It is not necessary to switch the display off while working on purge command. Will you please redirect us to the video where you've seen that...!

    Relaxation factor

    Nice Question...! For simple problems, you can keep the value of relaxation factor at its default one. As relaxation factor works on suppressing the solution (from previous iteration), surely it is going to take a lot of time. Taking the project span into consideration, you have to use it when it is really needed.

    Relaxation factor

    Generally, value between 0.2 - 0.4 provides good balance between achieving small progression of solution and extra compute time needed to achieve the convergence.

    Relaxation factor

    Relaxation factor is primarily a number which is used to converge the solution.

    Mesh Size

    Absolutely...! The mesh on the surface "one" is prescribed by relative mesh size. Relative mesh size of 0.125 is used in here. Assuming the largest length in the model to be one meter, this is multiplied by 0.125 (the no. mentioned earlier) to generate a surface mesh where the largest element is 0.125 (1*0.125 = 0.125). The resulting mesh may look like this-

    Mesh Size

    Interesting question...! When you’re fully aware of the size of model, just go for absolute. Absolute mesh size has a unit length which can be modified also. But in actual practice, you may have to do couple of iterations for meshing to the benchmark level (set by organization). In relative meshing which is found out by a factor (a number ranging from 0 to 1) multiplied with the largest edge length of the bounding box for each geometric face in the surface group, different mesh size maybe used for faces of the model.

    curvature refinement

    If you use curvature-based refinement on surfaces that have sharp curves, you must specify a reasonable minimum curvature size either globally. Otherwise, extensive amounts of mesh refinement will take place in that area. In general, it is the parameter which defines mesh refinement in sharply arched areas.
