EngiLab Products > Structural Analysis DLL Solvers

The heart of a Structural Analysis program is its Solver: The software engine that performs the specified type of structural analysis (linear static, non-linear, dynamic, modal, in 2D or 3D, etc), making all necessary computations in order to obtain the analysis results from the initial model data.

EngiLab Dynamic Link Library (DLL) Structural Analysis Solvers make it easy for anyone to apply structural analysis in their custom applications, written in Visual Basic, C/C++ and other languages, using the same analysis "engines" proven accurate, in use from thousands of users worldwide, within EngiLab products.

A structural analysis DLL Solver works as follows:

The Solver is a DLL file, that we develop for you, that must be added to your custom project. You can use your own programming language to make a Graphical User Interface for data input (pre-processing). The user can use your program to specify the model data (Nodes coordinates, element connectivity, materials, etc).
When the analysis must be carried out, your program calls the DLL Solver. The Solver contains all the necessary programming code that performs the specified type of structural analysis. It receives the model data in a specific format, makes all necessary computations and exports the analysis results (nodal displacements, element forces, constraint reactions, etc).
Then again, your program receives the analysis results, and it can represent them on screen for the user (post-processing).
This procedure saves you time, because you do not have to develop difficult, complicated and time-consuming structural analysis codes yourself, you just have to make the interface needed for the structural modeling.

Solvers Input and Output

DLL Solvers act as functions, that receive the Model Data as Input and return the Analysis results as Output.

Input (Model Data):
   Materials data
   Sections data
   Nodes coordinates and constraints
   Elements properties (Material, Section, type) and connectivity
   Loads data

Output (Analysis Results):
   Nodes displacements
   Element forces
   Constraints and spring reactions
