AW: Error when compiling an older version of the pencil code

[Matthias Rheinhardt]

Hi Yuvraj,

the first error in hydro.f90 is strange as it indicates an incoherence in  the code version you are compiling. You can avoid the error by 

real :: delta_u=1.

above the "contains" line in that file but it would be better to use a code version, which doesn't show this inconsistency. The other error is due to misbehavior of gfortran. You can suppress it by commenting out line 6731.

Best,

Matthias

Betreff: Error when compiling an older version of the pencil code

 

Hi all,

I was just compiling an older version of the pencil code using pc_build and I encountered an error as follows.

ar r magnetic.a nomagnetic.o magnetic/nomeanfield.o magnetic/nomeanfield_demfdt.o
ar: creating magnetic.a
hydro.f90:170:28:

Any help in this regard is appreciated.

Hi Matthias,

I was trying to integrate the local flame displacement speed (Sd) calculation into the chemistry.f90 using the species conservation equation that's when I encountered the problem. Thanks for the help. I ended up successfully integrating the same in my current version. I am able to write the Sd field as an auxiliary variable in addition to viscosity. 

Next, I need to calculate the sum of the calculated Sd field over the entire domain, similar to how TTm (print.in) is calculated. Although I would be using the sum to eventually alter the inlet x velocity but first wanted to check if the calculations are consistent.

I'm currently working on it. Let me know if you could help me calculate the same.

Thanks

Best regards,

Yuvraj
