This page will go over the basics of Paradigm and all the various setting you need to know about before creating your first simulation.

To create a new solver node you need to be in the SOP context in Houdini. Press tab to bring up the node menu and search for “Paradigm Solver” in the dialogue. Then click anywhere to drop the solver down.
<aside> 💡 Paradigm is not available in DOPs. It is implemented as a SOP node.

By default, the solver will set the start frame to the first frame on your timeline. You can change this to whatever start frame you want.
Time Scale will allow you to make your simulations faster or slower by globally changing the length of time of each simulation step.
If you have a fast-moving or high resolution simulation you can add more substeps to make the motion resolve better. Doing this will slow down the solver.
Division Size will control the target particle division size of the simulation. Smaller values will make the point cloud denser.
<aside> 💡
Not this is not the resolution of the voxel grid for volume related operations.

The Particle parameter is the number of particles the simulation can hold at the start. This is not a hard limit and the solver will increase it if it needs more automatically as the simulation progresses.
The Grid Resolution parameter controls how the resolution of the volume grid is calculated. You can choose different options depending on what is most important to you. You can have it automatically compute the size relative to the particle division size, or explicitly set it to a fixed value.
