      How to monitor boundary values on the two sides of a thin wall at specific locations or points?n

      Hello Kalyan, nMonitoring boundary values at measurement locations is often done by specifying the locations as Surface Points. However, this might result in deviations if the points are not exactly on the boundary. nAs the mesh is a discretized representation of the geometry, the sensor locations from the measurements might not be exactly on the boundary and thus result in errors. If the point is slightly outside the mesh then no value is returned. If the point is slightly inside the mesh the value is interpolated so it is not exactly the value on the boundary. nIn short, an alternative method is to create an Iso-Surface by coordinate on the selected boundary, which results in a line. From that either an Iso-Clip or another Iso-Surface by coordinate is created to extract a short piece or single point of the line. On this object the monitor can be defined.  For a thin wall, the temperature on the two sides of the thin wall are available as separate field variables Wall Temperature and Wall Temperature (Thin). The variable Static Temperature is the temperature of the adjacent cell. nI hope this helps.nRegards,nSuryan
