To begin, happy holidays to all...... For those whom have downloaded Lapsim from the bosch motorsport website, did any of you find the standard setup files and/or the example files that were supposed to be found in the 'vehicle para' folder? Just wondering here as I was not able to find any data for the sim to read. Thanks-Wil

[Greg Locock]

Yes, it works fine on my machines. There are 4 example cars (.mat) and a spreadsheet, in the vehicle directory.

Hmmmmmmm, interesting, as I have shortcuts that point to those files, but when I try to load them I get an error indicating that the files cannot be found. A shame because this seems like a great tool, and I'm very anxious to experiment. And if I spend more time fooling with it, my wife will likely poison me. If anyone has an idea what I might be doing wrong, let me know...

Did you get the files?

I notice that the vehicles as given do not have the downforce sensitive to ride height. You can switch that (rather crucial) option on from expert mode, I guess one of my jobs back at work is to come up with a guesstimate of the likely gain. Understandably he has not separated the undertray out specifically, so the number you type in is going to be a composite of the performance at each axle.

Greg, I apologize for not properly thanking you for sending the files-things have been crazy-so thank you very much. And as you indicated when sending them to me, my problem does seem to lie elsewhere; same results with the files you sent. Again, the circuit files open fine, the vehicle ones cannot be loaded. Curiously, if I browse to either set of files with Access, I cant open them inside access.......very strange. But thank you for your help-I'll keep trying as I'm anxious to learn from this program. Cheers, Wil

[Greg Locock]

They won't open in Access, they are Matlab files. You should be able to load them up into lapsim by clicking on the rectangualr vehicle button.

Hi Greg, yes I tried loading them inside lapsim first (using the vehicle button), and it was here that I received the 'files can't be found' error message. When I rt. clicked on the shortcuts, it indicated that they were MAT files (Access tables), so that's why I tried opening them in Access. I've not used MATLAB, so unfortunately I'm low on diagnostic abilities for this problem. I may try loading it on another machine w/ a different OS. Thanks again for your help-Wil

A MAT file is a Matlab binary format.

OK, can you get into a dos prompt, and get down into that folder, and then confirm that the files exist in DOS? they are about 11 kb long i think.

Failing that, expand your explorer pane to full size, click on view, click on details. That will show you the file size and dates

As a side note, LapSim is NOT a fully dynamic simulator, it works more by looking at a succession of steady states, so crucially shock aborbers don't matter.

[castercambertoe]

Checked the files in DOS-they're there....downloaded again, same results. Just the vehicle files fail to load. What OS are you guys running?

[Ben]

XP

Works OK in NT 4, and 98SE
