Description:
The second time-step of a run using the CrankNicholsonDdtScheme is not exactly correct. The attached fix resolves this problem and improves the handling of restarts and supports the change from other schemes to the CrankNicholsonDdtScheme scheme during a run.

Solver/Application:
All using this second-order temporal derivative.

Source file:
OpenFOAM-1.4/src/finiteVolume/finiteVolume/ddtSchemes/CrankNicholsonDdtScheme/CrankNicholsonDdtScheme.[HC]

Platform:
All.

Version:
1.4

Fix:
CrankNicholsonDdtScheme.H
CrankNicholsonDdtScheme.C

Iam installing OpenFOAM SW on a 64bit AMD machine with 2 processors. I did all the steps suggested by Hrvoje Jasak and everything worked.
(I mean the only test cases). I must say that I have to add different PATH for LIBRARY definitions to get the libraries get linked.Iam installing the SW for a user. I must say that I have NOT yet compiled the program on my machine till now.Iam installing OpenFOAM-1.4 on my machine.I want to know is there any tests which I can do to test the installation of SW? I did the the following test from icoFoam directory:
blockMesh . cavity
icoFoam . cavity
Both worked without error.
I have another question regarding the startup of
FoamX command. When I start the script I get the following error:

$strace FoamX

The above message repeats many times. I would like to know how I can overcome this error and what is the contents of the file "ns.ref". I donot have this file in the above directory.

I will appreciate very much your hrlp.

Kumar

Hello Henry,

If I'm only using icoFoam and interFoam (both in parallel), is there any way I can avoid recompiling everything? What libraries do need to be recompiled after using your updated CrankNicholsonDdtScheme.* files.

Thanks!

All the ddt functions are run-time selectable and hence built into the finiteVolume library so you only need to recompile that library.

Hello Henry,
I download your last version of CrankNicholsonDdtScheme.* and copy it in the folder:
OpenFOAM/OpenFOAM-1.3/src/finiteVolume/finiteVolume/ddtSchemes/CrankNicholsonDdt Scheme/.
then I compiles with wmake in OpenFOAM/OpenFOAM-1.3/src/finiteVolume following your advices to pUI|
but, I have an error message :
" (...)
lnInclude/CrankNicholsonDdtScheme.C:120: error: 'const class Foam::Time' has no member named 'startTimeIndex'
lnInclude/CrankNicholsonDdtScheme.C:121: error: 'const class Foam::Time' has no member named 'startTimeIndex'
lnInclude/CrankNicholsonDdtScheme.C:131: error: 'store' is not a member of 'Foam::regIOobject'
lnInclude/CrankNicholsonDdtScheme.C:149: error: 'store' is not a member of 'Foam::regIOobject'
make: *** [Make/linuxGcc4DPOpt/pressureTransmissiveFvPatchScalarField.o] Error 1
"
I use OF v 1.3, is it the reason of the problem ?
or maybe I made something wrong ...
OUPS !! I've got a doubt now ... is your modifications only for v 1.4 of OF ?

Thanks

Cedric
