2D Thermal is an add-on module to PLAXIS 2D. The thermal module is necessary when the effects of heat flow on the hydraulic and the mechanical behaviour of soils and structures need to be taken into account in geotechnical designs with PLAXIS. For full thermal-hydro-mechanical coupling the PlaxFlow module is required as well.

Seamless integration of thermal analysis

Temperature gradient is one of the main causes for movement of heat and water in soils. Since groundwater flow plays an essential role in the transport of heat in the ground, coupling between thermal and groundwater flow calculations, is necessary. The Thermal module seamlessly integrates this behaviour into your existing PLAXIS models.

Anticipate changing soil conditions due to climate change

Climate change is an important issue, especially in arctic regions. Thawing of permafrost gives rise to a whole new range of engineering problems. PLAXIS is equipped with features to deal changing soil properties due to temperature change, enabling engineers to anticipate and react to potential stability issues of for example foundation in arctic areas.

Optimise ground freezing design

Artificial ground freezing can be used to temporarily stabilise weak ground. As the temperature in saturated soil decreases due to freeze pipes, an ice wall is formed, making the soil watertight. Dry excavation is then performed to provide permanent stability measures. The complex interplay between the velocity of groundwater flow, temperature of the freezing pipes and their effects on the formation of the ice wall can easily be studied through the various boundary conditions this module offers.

Analyse stress rotation due to thermal loading

Coupling between thermal loading and mechanical process is required when the temperature change in soils results in thermal stresses. For example deformation of a navigable lock due to sunlight absorption when the lock is empty. Thermal boundary conditions including Climate allow PLAXIS to analyze  displacements, or the rotation of stress due to temperature changes.

    

TECHNICAL INFORMATION

Operating System requirements

Windows 7 Professional, Windows 8 Professional, Windows 10 Pro
Recommended: Windows 7 Professional 64-bit (all with latest service packs applied)

PLAXIS 3D 2016 requires a 64-bit operating system at the minimum

USB Port

1 port required for USB licence

Graphics card

Required: GPU with 256 MB OpenGL 1.3
Plaxis strongly recommends avoiding simple onboard graphics chips in favour of a discrete GPU from the nVidia GeForce or Quadro range with at least 128 bit bus and 1 GB of RAM, or equivalent solution from ATI/AMD.

Processor

Required: dual core CPU
Recommended: quad core CPU

Hard Disk

At least 2 GB free space on the partition where the Windows TEMP directory resides, and 2 GB free space on the partition where projects are saved. Large projects may require significantly more space on both partitions.
For best performance, ensure that the TEMP directory and the project directory reside on the same partition.

Random Access Memory (RAM)

Recommended for 2D: at least 4 GB. Large projects may require more.
Recommended for 3D: at least 8 GB. Large projects may require more.

Video modes

Required: 1024 x 768 pixels, 32 bit colour palette
Recommended: 1280 x 900 pixels, 32 bit colour palette
