Creating a material database

Recommended Posts

Hello all, 

How do I create a material database using a text editor such as Notepad or Jedit, so that I can include it in the Master model as an Include file. I need to create  a card for RADIOSS. Is there any documentation or videos that I can watch? 

Thanks in advance for your answer.

Hi @Pranav Hari

 

I want to know how to work with text files. For instance, I have come across a .k file which contains the material database, which I inlcude in the master model for LS-dyna solver. And similarly a .bdf file for the optistruct solver. How do I create one for RADIOSS, without using the GUI? 

 

Thanks

Hi vishruthdilip

 

 

.K file and .bdf files are input files of other solvers. Similarly, you have .rad file for Radioss which is a ASCII file. You can as well edit this file in the text pad or so and make changes accordingly. In your case, if you need to edit some material data, you should first have a reference .rad file (0000.rad) which is a starter out file. You can make changes to this starter out file.

 

Also have a look at the radioss files from the e-book https://altairuniversity.com/free-ebooks-2/free-ebook-crash-analysis-with-radioss-a-study-guide/ (page 35, Radioss files)

Hi @Pranav Hari,

 

So the simplest way of say creating a MAT/LAW2 would be to copy the Example, as shown in the picture below in the text editor ( .rad file )  and edit the parameters as required? Am i right?

Hi @Pranav Hari @karthikeyan Thangavelu,

 

I have created the include file. But when i import the solver deck, it shows the following error. 

 

Warning:  starter Input Deck contains Keyword   which is CURRENTLY UNSUPPORTED in HM present at line number 27
Summary:Feinput finished with 0 errors and 1 warnings.

 

My input deck has only 26 lines. 

I've also tried it with a more complex file which I could run before, but it shows the same error.

Hi vishruthdilip

 

I tried opening the files. It worked fine at my end. However, the error message appears. Try deleting the card which is marked on the image, export it as .rad file and import the new file again. This should import without any error message
