## Create a derivative function using Dymola

Sometimes it is useful to be able to determine the derivative of a function, for example when you require to use the derivative of the function directly. This post looks at how you can use Dymola to determine this for you while going through an example. Why calculate the...

## Basic Dymola Terminology

Like anything technical, there’s plenty of jargon surrounding Dymola and its functionality. While much of it is relatively self-explanatory, some may not be clear at first glance. In this blog post I will try to shed some light on basic Dymola terminology, and provide a few details on their...

## How to solve your own nonlinear equation

Whilst Dymola is good at solving nonlinear equations in models automatically, this post has a look at how to create a function that solves a nonlinear equation. A useful tool when required, as well as a way to get further insight into how nonlinear equations are solved. Why solve...

## Calculating partial derivatives of a model

Calculate partial derivatives of a Modelica model in Dymola.

## The Analytical Jacobian

Dymola is a tool built around advanced symbolic manipulation. Many solver algorithms and numerical methods are / can be utilized to solve the models created within Dymola. Many of the algorithms and numerical methods have substantial impact on the accuracy and speed of the resulting simulations. Jacobian matrices play...
