Saving Results from a given time step

[adasi11]

Hey,

I was wondering whether the following utility could be easy (or reasnobale) to implement:

Provided that a simulation reaches a given timestep, save the Vm in a similar fashion as the ECG (i.e., a text file with each row being a time step and each column an element in the mesh). So, basically, the same as the ECG function, but with the transmembrane voltage and from a given time step.
So, the user could specify when to save results (i.e., after t = 1000 ms) and wih a print_rate that could be different from that of the [save_results].

Thanks,
Albert

Hi Albert, that would be easy to implement. I think I can do this later today.

That would be fantastic, thanks!

Albert, for now, it is only possible to use the same print_rate, as the save_mesh_function is only called each dt that corresponds to the print rate. To use the new functionality just add the option extra_function_1=save_vm_matrix in the [save_result] section. A file called Vm_matrix.txt will be saved in the output_dir directory. You can use the start_saving_at option to define at what time this matrix will be saved. You can also use this function as a standalone save_result function.

In the future, I will add all save_functions to a static library, so it will be easy to reuse them in the custom_functions file, without duplicating code.

Let me know if this was what you needed.

My best,
Rafael
