[FAQ]

A transport variable (species) is created and initialized through a CSV file. It happens that the field is not properly initialized. Why is that? This may happen when the transport variable has a short name which leads to a possible confusion with another field. A typical example is when the transport variable is named C (standing for concentration, why not) and which leads to confusion with the COORDINATES field whose first letter matches that of the transport variable. Replacing C e.g. with Conc would be a convenient remedy. Along the same idea, species names that may be confused with possibly existing fields should be avoided. In other words, avoid names such as T or V as they may potentially refer to TEMPERATURE or VELOCITY respectively.
