[cellml-discussion] ABI CellML Meeting Minutes, 21st April 2010

>From what I recall, the IDA docs actually suggest that you use a separate
method (i.e. non-IDA) to get initial conditions, but I'll check through
them, just to see if my recollection is correct.

Can I suggest we please discuss this further on tracker item 2516
(https://tracker.physiomeproject.org/show_bug.cgi?id=2516).

Regards,
Randall
