runTimeModifiable yes; did not
 

runTimeModifiable yes; did not work with channelOodles solver. Is this normal? What should I do to make such option effective? The used timestep is just to check if the option is working, that is why it is big. Thanks.

Are you running an adjustable
 

Are you running an adjustable timestep? If so it will override deltaT to preserve the maximum Co number.

yes I'm running adjustable tim
 

yes I'm running adjustable timestep but the parameter that I changed during run time was maxCo so if the file is read before each time step, then the solver should allow for the new modified maxCo. It did not. Thanks for your help.

Change something else in the c
 

Change something else in the control dictionary while running to see if it gets read, like writeFormat. If this change doenst take effect then you have some timestamp issue. If it does take effect, your problem is that the maxDeltaT is overriding the maxCo.

In this case I can suggest is that you check the source code of setDeltaT.H to see how it works.

Hi, I had the same problem
 

Hi,

I had the same problem with turbFoam. I changed the turbFoam.C. Maybe you can get some hints how to change your channelOodles.C
