Finding Stable Points in a system of ODEs
04 May '12 19:02
We've been working on a new SBML interface to APMonitor Modeling Language that can solve very large-scale models in steady-state (dx/dt=0), dynamic simulation, parameter estimation, optimization, etc.
Once you've converted the SBML model to APM, it can be solved through a web-interface...
One of my students, David Grigsby, gave a presentation last week that explains some of the capabilities and future development plans...
We're looking for additional researchers to help benchmark APMonitor performance. For example, a complete simulation (to a time of 9000) with the ErbB model takes around 20 seconds. The ErbB Signalling model has the following characteristics:
We don't know if this is faster than other available software for simulation. Does anyone else have perspective on the simulation speed benchmarks for large-scale models?

Content-Type: text/plain; charset="ISO-8859-15"
I am simulating a model with ~200 first-order, non-linear system of ODEs. I want to know if there is any way I can find out:
1. If the model has stable points? If so, how many?
2. Is there a good software (free or commercial) for dynamical analysis of ODEs which can handle large no. of non-linear equations?
