Error with setting initial condition from previously obtained solution

Hello,

I am attempting to use a previously obtained pde solution as an initial condition. I keep getting an error that states:

"Error using pde.GeometricInitialConditions/precheckIC (line 217) Specify initial conditions as a scalar or a column vector of length PDESystemSize."

I figured this was something just with my code, so I attempted using the same function setInitialConditions(model,sol) using the code given in the setInitialConditions documentation (https://www.mathworks.com/help/pde/ug/pde.pdemodel.setinitialconditions.html), but the error continues to show up. This error does not occur when I specify the initial condition as a scalar or function, only when defining the initial condition as a previous result.

 I am using the R2016a version of matlab

Thanks! Ryan

Hi Ryan,

Ability to restart from previous solution was introduced in R2016b, refer to the release notes .

Please upgrade to a newer release, if you can, to use the nodal initial condition that would enable you to restart from a previous solution.

Regards,

Ravi

Thanks Ravi. It is a shame I overlooked that!
