1.	While solving a system of equations with the Thomas algorithm, in which order are the values of Pi and Qi found?(a) Backwards(b) Forward(c) Simultaneously(d) Depends on the problemI had been asked this question in semester exam.I want to ask this question from Discretization Aspects topic in section Basic Aspects of Discretization, Grid Generation with Appropriate Transformation of Computational Fluid Dynamics
Answer» Right ANSWER is (B) Forward For explanation I WOULD say: To find the current VALUES of PI and Qi, the previous values Pi-1 and Qi-1 should be known. So, this is started from the first equation and done in forward order.
