  1. Hello everyone, I want to create a script, which takes data from binary files (e.g. binout from LS-Dyna, it stores curve data), computes it (e.g. find the maximum value of a curve) and create a result file, which can be used in HyperView (e.g. as a result for a contour plot). To be more specific, I want to create a contour plot for spot weld elements, which contains maximum values (constant over time) of spot weld forces, which are given in a binary output file from LS-Dyna. I did not find an easy solution for this task, therefor I tried to break it down. This describes my plan backwards from the finish to the start: - To create a contour plot from custom data, I can use an XML file, which defines my datatype (see "HyperWorks Result Math/Creating New Datatypes") - To access data, which will be used for the new datatype, I can create a TCL Plugin or use TCL commands respectively - The data is contained in a binary file. I want to either use HW TCL commands to access the LS-Dyna binary output directly or use the commands to access an Altair Binary Format file (ABF), which might be easier - If I want to use the ABF file, I have to translate the LS-Dyna binary output file via HGTRANS first Further applications could be the storage of the computed values as *.csf file, therefor I am really interested in the reading of this data. Since I am really new to this topic, I would need some opinions and tips for this. Makes the whole process sense or is there an easier way? Which TCL or HW TCL commands can I use to access data in a binary file (LS-Dyna Binout or ABF)? Thank you. Update 1: I wrote a script to access curves, which are plotted in HyperGraph, and store them in a database array. Then I write the data into a CSV file, to evaluate it with Excel. I think this was the easy part. The next question is, how do I read curve data from binary files? Can anyone help?
  2. I want to export to STL binary, is this possible in hypermesh? I am trying to send an STL file of my model to a friend. When I export it as STL I can't open in other software to see if the file works. These include SolidThinking and even HyperMesh itself!!! When trying to open the STL ascii file in SolidThinking it doesn't work, is this because it's in ascii file? An error file comes up saying "save invalid elements to usermark?". It is quite a large file (8.1MB), is this the problem? Also, I want to export geometry as a STEP file but it can't saying "no geometric entities present for export". Any help is much appriciated
