Using CONSELF means entering a new mindset, a new philosophy of simulating. Therefore, in order to be able to read and understand the following tutorials, bear in mind the following key definitions:
Simulation: a mathematical procedure that allows to reproduce in a virtual environment - software - a physical behavior. Compared to laboratory tests, it is a quicker and cheaper process. Ultimately, simulations help engineers validate the hypothesis behind every design phase.
Case: any single test performed by using a simulation system.
Step: any single phase the user has to accomplish in order to run a complete case simulation.
Although each CASE simulation depends on the users’ needs, CONSELF defines an identical path for every simulation. This path is divided into the following STEPS:
Obviously, in order to perform a certain STEP all previous ones must be completed. Furthermore, it is possible to run multiple STEP from the same precursor (i.e. run multiple CFD by using the same mesh). For this reason, when starting a new STEP it is always required to link it to a precursor, as shown in the picture.
In the present manual, each of these steps are accurately described and displayed, with examples taken form CONSELF-run tutorials.
After having logged in, the CONSELF dashboard appears on screen. On the menu on the left side, the last entry is the Simulations tab. Click on it to be redirected to the simulations front page, shown in the following figure. There are three main sections: two in the upper part and one in the bottom part as also highlighted by the following image.
When defining a new case, the user is requested a certain number of inputs:
|Sector||Application name||Main features|
|CFD||GENERAL||Compressible and incompressible with steady and transient features.|
|CFD||TURBO - SRF PUMPS||Single reference frame (rotating) incompressible flow. Steady simulation for pumps.|
|CFD||OIL&GAS - FLOW WITH PARTICLES||Incompressible flow with with solid particles transported.|
|CFD||OIL&GAS - MULTIPHASE FLOW||Incompressible flow of two inmiscible species.|
|CFD||HVAC - PASSIVE SCALAR TRANSPORT||Passive scalar transport for compressible and incompressible flows.|
|MECH||STATIC - LINEAR ELASTIC||Mechanical simulation using an isotropic linear elastic material.|
|MECH||DYNAMIC - FREQUENCY||Modal analysis of an isotropic linear elastic material.|
Type the first part of the application name to filter the available choices.
On the right handside, it is possible to access previously created simulations which have not been erased yet. All the data are in fact stored using the cloud space available according to your active subscription.
It is possible also to have an overview of recent activities in the platform, i.e. finished steps and cases using the Activity button on top of this page. This button opens a further window which shows a list of recently submitted steps, with the information regarding each of them.
The bottom part of this page is actually peculiar because it gives quite a few information about the steps which are submitted to the system to be processed.
It is important to note that there is no limit of number of contemporary running steps a user can have, as long as there are sufficient credits.
CFD and FEM simulations are quite expensive in terms of storage resources. According to the subscription you are using, a limit is applied to the storage available to your user. If you filled the amount of storage available it is possible to:
Under the storage page, the user can find analytical data about his storage usage. At the same time it is possible to delete old cases by selecting them one by one. In this way you are removing non necessary data and you can free more storage space for future cases.
CONSELF guides you through the simulation literally step by step; in fact, in order to complete a simulation, the user has to go through several steps, each of which fulfills a precise task. Given the high flexibility of this method, users, less experienced as well, may take advantage of this philosophy of work: they have the ability to control the process, start over or modify what had previously been done. When a CASE is opened, a STEP interface is accessed, as shown in the picture below.
The application is generally divided into two sides:
A fundamental part of the application is given by the Steps completed button, which gives access to a detailed summary table of the performed steps within the current case. After clicking this button a new windows pops-up with one row for every step submitted in the current case.
The data available for each step are:
