Introduction
Fire is visualized using ParaView's volume rendering functionality. Unfortunately fire simulations are extremely large. Fortunately, we can use disk_out_ref.exo as a substitute dataset.
Note: Volume rendering is very resource intensive. It is possible to display a dataset using surface that chokes using Volume Rendering. The solution is to grab more nodes of your cluster (thus picking up more memory).
Note: Currently (3.6.2 and 3.8.0), volume rendering only works on one block at a time. Thus, before volume rendering multiple blocks, run the "Merge Block" filter. This should be fixed in a future version of ParaView.
- Start ParaView
- Open disk_out_ref.exo. Select all variables. Apply.
- Color by temperature.
- Representation by Volume Rendering.
Since this tutorial is for rendering fire, we need to make disk_out_ref.exo look like fire.
- Edit Color Map
- Choose Preset. Choose Black-Body Radiation. OK.
