When debugging a model, a de-cluttered messages log window makes it easier to identify what the important/critical problems are that Dymola has found with the model. How can we de-clutter a log window though without loosing valuable information Dymola tells us about the model? There will be text in...
This blog post describes a procedure to debug a crank-angle resolved engine model (CAREM) in Dymola. It helps narrow down to the cause of the problem in case the engine runs but does not produce the expected results. A CAREM is a multi-domain (mechanics, fluids, thermal, electrical) model so...
Dymola provides a means to measure where the CPU time is being spent in the model code execution. This feature is known as profiling. Profiling is described in Section 5.7.5 of the Dymola User Manual Volume 1. This blog article supplies further information. Profiling is implemented by inserting timers...
Models of physical systems with state logic and time based discontinuities can often produce events in Dymola. These events can have a significant impact on your simulation performance, so it is important that we understand where these events are coming from in the model. In this blog post I’m...
