2. Usage Overview

2.1 Construction of awFEM

This application software is constructed with views corresponding to functions introduced in previous section.

The top view (root view) opened at just launch time of the application, manages awFEM documents.

There are four types data - geometry, mesh, analysis condition and analysis result - for FEM analysis, this app. manages documents with these data as one document. Geometry data are inputted at the first time, then a mesh data generated from the geometry data is appended into the document. Moreover, analysis conditions are added, and finally, analysis results are attached after FEM analysis.

Root view shows document icons individually for categories as followings.

Modeler, Mesher, Conditioner or Visualizer is launched when an icon in Model, Mesh, Condition or Result category is double tapped or is tapped after selecting of the icon.

2.2 Procedure Overview

In this subsection, the concrete procudure overview is indicated with Fig.1. Please refer to after this section for the detail of operation in each of the stages(Moder, Mesher, etc.) of FEM.


図 1 Procedure Overview

(1) New Model

Create new document by tapping on the top bar of root view. The empty document is placed in the Model category as a gray icon.

(2) Model Creation and Editing

In order to perform the input and editing model geometry, open the Modeler by double tapping on the icon or tapping on after selecting the icon.

In addition, you can analyze only one object with no separate area as a model. The existence of holes in a model are permitted.

(3) Copy to Mesh Category

Document with model geometries can be copied to Mesh category. Select the document's icon in Model category, tap and select "Mesh Creation".

(4) Mesh Generation

Open the Mesher by double tapping an icon in Mesh category or tapping after selecting the icon.

After mesh generation, close the mesher.

(5) Copy to Condition Category

The document with mesh data can be copied to Condition category. Select the icon, tap and select "Condition".

(6) Conditioning

Open the Conditioner by double tapping an icon in Condition category or tapping after selecting the icon.

Close Conditioner after setting boundary conditions, load conditions or material properties.

(7) Execution of FEM Analysis

"FEM Analysis" can be selected if is tapped for a document with condition data. Select "FEM analysis" to run FEM solver. A document added the result data will be stored in Result category.

(8) Visualization of Result

Open the Visualizer by double tapping an icon in Result category or tapping after selecting the icon.

The distribution of physical quantity(displacement, strain, stress, etc.), or deformation of the object can be recognized.

2.3 Numeric Input Method

A custom keyboard with calculator function is opened when numeric value input is required. A equation with brackets '(' and ')' can be supported. '=' key executes calculation, and '↵' key executes calculation and ends enter of value.
