Re: [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).

Subject: [TRNSYS-users] error creating a wall type Trnsbuild

 
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,
