No more Nanostep solvers available

Hi, when I use four DABs with Nanostep solvers and run real-time simulation, I encounter the error ‘No more Nanostep solvers available.’ My PLECS version is 4.9.4, and I am using RTBox1. How can I resolve this error?

From the RT Box manual: “The number of Nanostep power modules that can be simulated within one model is limited. Each Nanostep power module is associated with a weight (a simple dual active bridge, for example, has weight of 1, a full-bridge resonant converter a weight of 3 - see the documentation of the respective power modules). RT Box 2 and 3 allow the simulation of Nanostep power modules with a total weight sum of 6, for RT Box CE and 1 the total weight sum is limited to 3.”

So, on RT Box 1, you are limited to 3 DABs. RT Box 2 or RTBox 3 would allow you to run 6 DABs in parallel.
