How to write the chech_time of the condtion in Group

[Binghui Cui]

Dear developers,   

      I  want to run a specific set of equations only every 20 iterations.  I know a Group takes a keyword argument called condition. But I don't know where the check_time is written. Who can give me an example. 

Thanks in advance!

Best,

Cui Binghui

Hi,

There is an example here:

https://pysph.readthedocs.io/en/latest/design/equations.html#conditional-execution-of-groups

For an executable version see the test here:

https://github.com/pypr/pysph/blob/master/pysph/sph/tests/test_acceleration_eval.py#L586

The callable can also be a method, so you may define a method on your Application and pass that long to your Group.

cheers,
Prabhu
