On a few machines, a licensing error occurs when first running PyroSim. If you receive a message such as "NETWORK: Network drivers appears to not be serving this directory" or "INIT_NOT_SUCCEEDED", please perform the following steps:
Go to the installation directory C:\Program Files\PyroSim\
In this directory, double click (execute) the file SETUPEX.exe
You should now be able to run PyroSim and complete the registration process.
PyroSim utilizes many advanced graphics card features in order to provide accelerated display of models in three dimensions. If you have problems with display, such as corruption of the image when you move the mouse, go to File->Preferences and turn off the fast hardware drawing options. This will disable the image caching and force PyroSim to always re-render the model. This should correct any display problems at the expense of speed.
You can also turn off graphics acceleration by starting PyroSim in Safe Mode. Select Run, All Programs, PyroSim, and then PyroSim (Safe Mode).
If you encounter this problem, please let us know the make/model of your video card and what video driver you are using. That will help us improve the faster version to work on more computers.
When running large models, it is possible that an out of memory error will be encountered. If this occurs, you can increase the default Java heap size. In our experience, the maximum size can be specified to approximately 70% of physical memory.
To specify the memory, you can either run from a command line or change the shortcut properties. To run from a command line, open a command window and then go to the PyroSim installation directory (usually C:\Program Files\PryoSim). Execute PyroSim on the command line using a -mem flag. For example, pyrosim -mem1200 will request 1.2 GB of memory.
To edit the PyroSim shortcut properties, right-click on the PyroSim icon, select the Shortcut tab, and then edit the Target by adding a space and -mem1200 to the end of the Target. A typical Target will then read "C:\Program Files\PyroSim\pyrosim.exe" -mem500.
