Public Beta 5 (2020.11.19)

Welcome to the Public Beta 5 of SIMBA. There are a few updates that we hope you will like. If you haven’t yet, be sure to download it. The complete list of changes is available here.

New Induction Machine Model

A new Squirrel Cage Induction Machine model is available in the Electrical>Motors library.

New non-ideal transformer model

A new 2 Winding, non-ideal Transformer model is available in the Electrical>Transformer library.

Model parameters syntax

Model parameters can now use metric units and mathematical expressions.

Accepted suffixes are:

Suffix	Coefficient
p	10E-12
n	10E-9
u or µ	10E-6
m	10E-3
k	10E3
M	10E6
G	10E9

Simple Mathematical expressions can also be used in parameter evaluations.

Basic operators (+, -, *, ^, !), constants (pi, e...) and math functions (sin,cos...) are supported.

Important

Expression are evaluated when simulation starts and a Syntax error is thrown if it can't be processed.

Division

A new Division control model is available in the Control>Math library.

New Example: Induction Motor Drive with v/f control

This example shows an Induction Motor Drive with v/f control.

Backward Compatibility

Important

Due to changes in our database format, SIMBA Beta 5 can't open files saved in previous versions. If you wish to convert a file to the new version, please send it to manu@aesim.tech. This is the last time backward compatibility is broken.

Quality of life

In Beta 5, several bugs are corrected and the general stability of SIMBA is improved.

Roadmap

If you are interested, you can check our roadmap and a public GitHub project is available to share ideas, report bugs, and suggest new features.
