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
