COMSOL Reveals Unknown Effects in Process Instrumentation

In new-product and technology development, the first step is to analyze and optimize a basic concept. When working with modeling software, we can quickly obtain initial results by reducing the problem to a 1D model, with which we can often understand a process underlying physics.

An attractive feature of COMSOL Multiphysics is its ability to solve 1D problems, which reduces the debug time to practically zero when we extend a model to 2D or 3D.

These techniques proved valuable in modeling a next-generation pressure rate-of-rise device.
