Simulation file extention

ar011 · 21 August 2024 06:27

Hello, does anyone know the extension of the file saved in data>Testrun after the simulation? if so, how can i generate this extension using matlab?

Could you explain this in more detail? What are you trying to do?

Usually TestRuns don’t have an extension such as .txt or .dat, instead they rely on a FileIdent writen in the first few lines of the file. For example:

FileIdent = CarMaker-TestRun 12

I am trying to generate and ASCII text using matlab with the same format of the testrun, and I want to use this ASCII file generated by matlab to run the simulations in CarMaker

Actually it almost worked,now im getting this error which I am finding it difficult to solve!

It sounds like you’re dealing with a complex task. Based on what you’ve described, you might be aiming for one of two approaches:

Creating a TestRun from scratch: If this is the case, you’ll need a deep understanding of the entire CarMaker TestRun structure, including all keys and parameter settings. This approach requires a lot of trial and error, or you’ll need to study multiple TestRun examples to get it right.
Modifying an existing TestRun: If you’re only changing a few parameters, like the road length, this is more feasible. However, you’ll be limited to the predefined road setup.

Which of these two methods are you planning to use?

The second options suits me well!, but do you know why, the screenshot which I posted, throws a lot of errors like those?

From what I can read, ir appears that you entered a bunch of duplicate or incorrect keys. Could you share your file here? Just be sure to change the extension to .txt, so that you are able to upload it.

Sorry Since I am new user, i cannot upload the file! Ill copy the content here!
