Open source community is getting wider, and people who used to provide libraries and solvers to the commerical softwares are releasing or re-coding their bundles which presents free to use software, or mainly people nowadays tends to contribute in open source projects more than the past.

Salome:
Salome is a open source CAD application which is sufficient for basic to advanced needs.

Calculix:
A Finite element analysis software which runs with input files similar to the structure of Abaqus commercial FEA software.

CALCULIX: A Three-Dimensional Structural Finite Elemente Program

FeNICS:
Finite element development library which either allows of using existing elements or creating new elements for special needs or uses.

OpenFOAM:
open source CFD tool, also supports solid analysis which is based on Finite volume approach, some modules which enhances OpenFOAM or GUI which automates the usage (since OpenFOAM is mainly text based) and uses Open source CAD tools to visualization.
OpenFOAM is becoming more user friendly and stable, providing sufficient tools similar of its commercial alternatives, the community is also expanding.

ParaView:
Data visualization and statistics software, used to generate pretty colourful plots from meaningless numbers.

ParaView - Open-source, multi-platform data analysis and visualization application

ParaView was developed to analyze extremely large datasets using distributed memory computing resources. It can be run on supercomputers to analyze datasets of petascale size as well as on laptops for smaller data.
