Hello to all friends This error has been observed in my simulation for a thermal area:
Severe ** CTF calculation convergence problem for Construction="FLOORCONSTRUCTION(1)".
** ~~~ ** ...with Materials (outside layer to inside)
** ~~~ ** (outside)="FLOORMATERIAL FOR CONSTRUCTION(1)(2)"
** ~~~ ** The Construction report will be produced. This will show more details on Constructions and their materials.
** ~~~ ** Attempts will be made to complete the CTF process but the report may be incomplete.
** ~~~ ** Constructs reported after this construction may appear to have all 0 CTFs.
** ~~~ ** The potential causes of this problem are related to the input for the construction
** ~~~ ** listed in the severe error above. The CTF calculate routine is unable to come up
** ~~~ ** with a series of CTF terms that have a reasonable time step and this indicates an
** ~~~ ** error. Check the definition of this construction and the materials that make up
** ~~~ ** the this-> Very thin, highly conductive materials may cause problems.
** ~~~ ** This may be avoided by ignoring the presence of those materials since they probably
** ~~~ ** do not effect the heat transfer characteristics of the this-> Highly
** ~~~ ** conductive or highly resistive layers that are alternated with high mass layers
** ~~~ ** may also result in problems. After confirming that the input is correct and
** ~~~ ** realistic, the user should contact the EnergyPlus support team.
Next, I will put the osm file related to the surface, thank you for your guidance
