\"\"<\/a><\/p>\nThis example in Altair Exchange<\/a>\n

Finally, I read how to write a script for HyperMesh in python. In this example, the script reads the coordinates of points from a cvs file.<\/p>\n

\r\nimport os\r\nimport hm\r\nimport hm.entities as e\r\nfrom hwx import gui\r\nimport csv\r\nmodel=hm.Model()\r\nos.chdir(r"D:\\projects\\wordpress\\ex431")\r\nwith open('ex431_coordinates.csv', mode ='r') as file:\r\n  lines = csv.reader(file, quoting = csv.QUOTE_NONNUMERIC)\r\n  for line in lines:\r\n      nodeNew=e.Node(model)\r\n      nodeNew.localcoordinates = line\r\n<\/pre>\n
It feels like the python code is translated into a tcl script and then executed in HyperMesh. Because HyperMesh continues to record executed commands in this form.<\/p>\n
