One of the small problems I find with analysing designs modelled with Modelica is the slow read of large result (*.mat) files. The same issue appears with both Dymola and MathModelica. If the model has many variables/parameters, and the result file is large (>100Mb? ) and I choose a variable to display (or do a zoom on a part of displayed variable) I find the PC locks up until the hard drive catches up. I think the solution might be (freeware) RamDisk for Windows, which I found discussed the other day on the LTSpice forums. The original link to the freeware is:
RamDisk link
There are instructions on how to use the RamDisk in the discussion link at the bottom of the linked page, I'll repeat them here for completeness:
CODE
OK, here is the latest file and how to install;
1. download the updated version at this link;
http://vista.inoxa.de/Dateien/Gavotte_RAMdisk__v.1.0.4096.4_25.01.2008.zip
The version posted here might also work, but anyway. Extract the archive to a directory.
2. Go to the Control Panel and click Add Hardware
3. Click Next and wait for the search to complete.
4. Choose "Yes, I have already connected the hardware" and click Next
5. Scroll to the very bottom and highlight "Add a new hardware device" and click Next
6. Choose "Install the hardware that I manually select from a list" and click Next
7. Wait for the search to complete and click Next
8. Highlight "Show All Devices" and click Next (warning: this part may take a few minutes)
9. Click Have Disk. (Important! Be sure not to click on anything else or scroll through the lists before you click Have Disk. Doing so will screw up this process.)
10. Click Browse and locate the folder you saved the rramdisk.inf file in, select ramdisk.inf and click Open
11. Click OK, then Next and Next again.
12. Click Continue Anyway if a warning pops up and then Finish
13. Right click on the "ram4g.reg" file in the extracted directory and "merge".
14. Now when you launch the ramdisk.exe utility, you should be able to see the options properly enabled. Set the desired ramdisk size and click OK. It should be ready to use at the default drive R:
