These operations include the discretization of equations and variables, the computation of the coefficients, the assembly of the linear or nonlinear systems, the solving of the systems, etc.

On the basis of numerous fluid simulation experiences, researchers have discovered that many common operations can be abstracted to form a general fluid simulation framework. In addition, it is noteworthy that the parallel performance of Masor is decided by a solver. The simulation results are regarded as physically reasonable by many studies, which verifies the correctness and effectiveness of the general framework. As an application of the general framework, a parallel 3D simulator for matrix acidization called Masor is developed. With the help of a field-based general framework, it is anticipated that the parallel codes of fluid simulations can be generated easily and quickly.

However, very few studies have noted this advantage, and therefore, this work attempts to fill the void. In other words, because of the newly defined 'fields', a series of operations in fluid simulations can be simplified and unified. Due to the convenience of the field operations, parallelization of the framework can be realized on both the OpenMP and MPI levels. Moreover, in response to the urgent need for large-scale fluid simulations, parallelism is integrated into the framework. Thus, fluid simulations can be performed under a field-based general framework.

Furthermore, all of the operations can be attributed to the operations 'in the field', which is an abstract concept derived from the equations and variables.
