| Summary | 0002889: #calc converts all variables to float | ||||
| Description | #calc is a great way to perform simple calcs on the fly, and thus avoid hand calculation errors However, I have noticed a strange behaviour when I use variables that have small values. For example, if I have some parameters defined in a file: // material properties nu 1.0e-8; // data for gradient calculation U0 1.0; dUdx #calc "$U0 / $nu"; which is then #include-d in a dict, then I get a floating point exception. Looking into the dynamicCode generated: dynamicCode/_895f27c8e0b93b41af125bc39eee9041e7fd19d5/codeStreamTemplate.C: os << (1.000000 / 0.000000); i.e. the doubles have been printed in some kind of %f format and reduced to zero. | ||||
| Steps To Reproduce | #include a file, with some parameters which are calculated, inside a dict run an application which accesses this dict I've attached a very simple example to demonstrate this | ||||
| Additional Information | Obvious workaround - change units (or non-dimensionalize) to eliminate this possibility | ||||
