Please, help me: I want to optimize a model. I am using Matlab for the optimization, Hypermesh as a pre-processor for my model and Abaqus as my FEA solver. I want to control all the operations in Matlab. I don't want to open Hypermesh and Abaqus. I have found a way around Abaqus. But I am having a challenge with Hypermesh. Directly from Matlab command, I want to call Hypermesh to execute my TCL script and output Abaqus input file. I want to run this process for many iterations by changing my mesh size in TCL script, thereby generating Abaqus input files of different mesh sizes.
This is my Matlab script for Hypermesh:
clear all;
clc;
hypermesh_bin='C:\Program Files\Altair\2017\hm\bin\win64\';
%enter the directory for the hypermesh executible
cd(hypermesh_bin);
run Hypermesh
dos ('C:\Program Files\Altair\2017\hm\bin\win64\hmopengl.exe&')
% run .tcl file (the name of my tcl file is comm)
dos_command = ['hmbatch-tcl' , 'C:\Program Files\Altair\2017\hm\bin\win64\comm.tcl'];
dos (dos_command)
I am getting this error:
ans =
0
The filename, directory name, or volume label syntax is incorrect.
ans =
1
Please, help me: kindly tell me what I am doing wrong.
Also, in order for us to have more discussion, I will appreciate it if you can send me an email, if you have worked with hypermesh directly from Matlab or you know how to do it. My email address is: [email protected]
Thank you.
Which line is failling?
Why there is an '&' in your path? (dos ('C:\Program Files\Altair\2017\hm\bin\win64\hmopengl.exe&'))
Hi Maxime, Thank you so much for the reply. The script ran when I made this into a batch file (sample.bat):
"C:\Program Files\Altair\2017\hm\bin\win64\hmopengl.exe" -batchmesher -noconsole -tcl "C:\Program Files\Altair\2017\hm\bin\win64\comm.tcl"
and ran system('C:\sample.bat &') from matlab command. Windows command prompt (cmd) comes up but I did not see any result.
Please, find my attached Abaqus input file and tcl command script. I want to generate several Abaqus input files of different meshes (mesh sizes of 1-3 at an increase of 0.2 for each iteration). After each iteration, the abaqus input file generated will be exported and save with a name which will make it easier to recognize the mesh size. I want to control everything from Matlab. Please, I need help with the implementation. Thank you.
