running simulation with different initial condition without compiling #157

arnabbandyopadhyay commented 4 years ago

Hi D2D team, I want to check the dynamics starting from different initial conditions keeping parameters, observables same. What I want to implement is the following:

arInit arLoadModel(deffile); arLoadData(datafile); arCompileAll;

for i=1:100 modify initial condition arFitLHS arPlot store data end

computation time is very high if I compile inside the for loop. Which variable do I need to modify for changing initial condition, or is there other way to implement this?

Thank you

Hi arnabbandyopadhyay,

if you do not specify the initial condition of an observable in the CONDITIONS section in the data or model def file, D2D will interpret the initial condition as a parameter that can be estimated alongside the other parameters of your model. To set it to a fixed value, you may use arSetPars with the qFit argument set to zero instead of "modify initial condition" in the pseudocode you provided.

Best, Adrian
