Inconsistent lookup for read/write data in CHT and FSI

[MakisH]

For temperature and heat flux, we are checking whether the field name is exactly matched in the config:

calculix-adapter/adapter/PreciceInterface.c

Line 624 in 4496e8f

if (isEqual(config->readDataNames[i], "Temperature")) {

For other fields, we are checking whether the field name just starts with this prefix (similar behavior as in the OpenFOAM adapter), sometimes with a trailing -, sometimes without:

calculix-adapter/adapter/PreciceInterface.c

Line 37 in 4496e8f

precicec_createSolverInterface(participantName, adapterConfig.preciceConfigFilename, 0, 1);

calculix-adapter/adapter/PreciceInterface.c

Line 654 in 4496e8f

} else if (startsWith(config->readDataNames[i], "Displacement")) {

Additionally, data names are hard-coded for preCICE:

calculix-adapter/adapter/PreciceInterface.c

Line 628 in 4496e8f

interface->temperatureDataID = precicec_getDataID("Temperature", interface->nodesMeshID);

Finally, this error message is rather confusing:

calculix-adapter/adapter/PreciceInterface.c

Line 662 in 4496e8f

printf("ERROR: Read data '%s' does not exist!\n", config->readDataNames[i]);

"Does not exist" made me think that I still needed to specify it somewhere. However, it just means that the adapter does not know how to handle it.
