Verification of transport codes by the method of manufactured solutions: theattila experience

摘要

We extend the Method of Manufactured Solutions (MMS) to the verification oftransport codes. We derive analytic fixed sources required by the MMS procedure for several types of transport problems and apply the method to the Attila transport code. By means of this method we discover and correct several coding mistakes in Attila and ultimately verify its correct implementation for the problems studied. Our studies reveal that the MMS procedure is a useful tool for transport code development.
