Hello, I want to build a gas turbine which operates at different altitude and I tried by using COESA model available in Simulink as it seemed very efficient as COESA model computes all atmosperic condition as the altitude changes. However, the connection between COESA model to Simscape was not possible. Would there be any alternative or solution?

More details would be helpful for the community to understand your problem better. If you could share what would be the inputs and output of the COESA model in Simulink, it might be possible to set up ideal sources and sensor blocks as the interface between Simulink and Simscape. Numerical performance of the resulting model is hard to predict though, lol.

The COESA model takes as input the height and outputs temperature, speed of sound, air pressure, and air density all as Simulink signals.

All you have to do is convert those Simulink signals to physical signals using the Simulink-PS block. When you insert the block, a diagnostic will help you set the units.
