[TRNSYS-users] error creating a wall type Trnsbuild

Amandine,
 
Check the thicknesses of your wall layers, layers that are too thin are
generally the cause of this error. If you've got any really thin layers,
consider using a massless layer and just define a resistance for it, as
its mass is probably negligible (which is why the transfer functions
freak out).

Dear TNRSYS users,
 
I created  walls in my TRNBuild simulation and an error message appears
when registering:"Error creating the wall transfert function
coefficients: Unable to find a root after indication that a root exists.
Maybe the timebase is too small. Please, check the INF-file further
information."
I do not see where is the problem. Thank you for your help.
 
Best regards,
