Hi Foamers,

I try to implement a variable time Step in the controlDict with the #codeStream directive based on the actual time. Something like

this->db().time().value()

produces the error massage "invalid use of ‘this’ in non-member function". Does anyone have an idea to get a reference to time?

Thanks and best regards,
Jan

May I ask if you have solved this problem? I have also encountered this problem.

sorry, but It's has been to long, can't remember. But as far as I know, there is now a functionObject available to control the time step. May this is helpful for your requirements.



Best,
Jan

Thank you very much for your help. I will try this method.

Hi

Can't you access time() of db() with the following code?

const IOdictionary& d = static_cast<const IOdictionary&>(dict);
scalar t = d.db().time().value();

Thank you very much for your help. I'm a novice. I've tried this method. It works. Why?
I can use scalar t=this ->db(). time(). value() in the u file;
However, it is not allowed in the coalcloudproperties file.
In addition, vectorField&field=* this; The same problem will arise.
Thanks and best regards,
