Computing CFD solutions in parallel by distributing the mesh across several processes is based on the functionality of data parallelism concept that applies numerical methods identical to serial solutions. The communication between processes make sure of consistency with serialised solution.

Every workstation requires Message Passing Interface (MPI) to run the parallel server. There is a list of machines on which you wish to place processes by starting a Cluster of Machines Manually and prescribing hosts where processes start. Using batch management system, which manages the job, allocating it to specific machines when they become available based on the requested resources. There are the servers as a set of homogenous machines. The availability of licences and various other user requirements should be coordinated with the capabilities of the hardware and effective utilisation of the gear must be done. There is a sophisticated solution for assigning the computing tasks in a batch management system, through installation and configuration techniques. The installation and implementation of a Batch Management System, in a Linux environment with a streamlined and effective scripting technique is to keep the workstation busy. It can thus be difficult to use the hardware effectively. Different batch systems like SLURM, PBS or Grid Engine run Simcenter STAR-CCM+ in batch mode. These are high performance based computation clusters, when there is sharing of servers with multiple users.

Installation of SLURM batch management system

  1. Install SLURM package using MUNGE service for authentication within a group of hosts.
  2. Configure SLURM queue setup using a SLURMs configuration file by adjusting the compute nodes section.
  3. Start the MUNG service and check it for effectiveness.
  4. Then set the machines idle to queue up jobs.

The combination of bash script and macro java allows least user interaction for a job. With the endless loop of script possibly be removed the case statement would be scheduled by a crown job.

With many options at bay it is important to choose the one that caters to all your needs and has more strengths than weaknesses. Choosing the right software for the main purpose is essential to realize elements of ideas without wasting time using the wrong tool. Fluidmech has one of the most robust suites of features and workflows that users can access in a single program, it is the best choice for a feat that increases efficiency, low cost of entry and approachable interface. Siemens has Fluidmech as its authorized partner, NX and Solid edge that tackles 3D modelling in Fluidmech in a number of different ways like digital sculpting, mesh-based modelling, and parametric modelling. It is hard to convey just what sets Fluidmech apart.
