We are glad to announce the launch of the new version of THERCAST®. Originally used mainly in the steel industry in order to study ingot casting and continuous casting, this solution is now being introduced to the foundry casting market, offering founders a new simulation tool for greater performance of cast parts.
THERCAST® simulates all stages from the casting until the end of the solidification. This new version offers simulation templates to each process such as sand or shell casting, high-pressure or low-pressure die casting, investment casting, centrifugal casting, etc.
The software is able to combine all physical and metallurgical phenomena by solving both the "Fluid Mechanics" part and the "Solid Mechanics" part. At any time during the casting and at any point in the part, the software precisely determines the local state of the metal (liquid, mushy or solid) and manages all interactions with the components of the mold (cores, pins, etc.). This approach provides increased reliability in predicting molding defects (shrinkages, gaps, cracks, etc.) and guarantees that peeling off the mold wall are dynamically taken into account (air gaps).
The graphical interface, unique to all foundry processes, makes it easier to set up data and analyze the results, in order to, for example, visualize in a single click the shrinkage, porosity or even the evolution of the material front.
Unique and business-oriented functionnalities
- In high-pressure die casting, THERCAST® stands out with a definition of pressure rail in accordance with real conditions and with a faithful representation of the metal pouring into the chamber; this makes it possible to simulate precisely all the phenomena related to each stage of the process from the initial dosage to filling the cavity and the final maintenance of pressure to compensate the shrinkage.
- In sand or shell mold casting, the integration of foundry filters makes it possible to accurately represent the flow of liquid metal and in particular the reduction of turbulent flows.
- The new version of THERCAST® also makes it possible to configure the inlets with precision to better represent the process as a whole.
- The new solution of self-adapting remeshing FORCE (Fully Optimized foR Computation Efficiency) saves precision and computation time. This functionality gives the possibility of faithfully detecting defects and their propagation, but also to perfectly model turbulent flows.
Efficient modeling of radiation phenomena for investment casting
This particular process requires the creation of a ceramic mold called a "shell", allowing to cast several parts to be molded in in a cluster shape, from a wax model. Thanks to a dedicated functionality, THERCAST® allows the user to easily create this shell from the CAD model of the cluster by considering the total thickness of the successive layers deposited during the sandblasting phases.
THERCAST® also takes into account the thermal and mechanical interactions resulting from self-radiation. It accurately represents the radiation heat transfer, very useful for studying investment casting or cluster casting or for studying the cooling phases. Read more
reduced computation times in continuous casting
Thanks to its thermomechanical liquid/solid coupling, THERCAST® makes it possible to study all types of phenomena in continuous casting: ladle and tundish flow, primary and secondary cooling, deformation in contact with rollers and spray-induced cooling, etc.
Transvalor has also developed a new method called "Global Slice Computation" to significantly reduce computation times in continuous casting. This method has proven its worth, especially for an industrial case of soft reduction whose computation time has been reduced from 7 weeks to 5 days. Read more
A modular offer integrated within the Transvalor suite
With this new version, Transvalor is launching a new modular offer according to the processes chosen by the user and the level of functionality desired. THERCAST® can also be used with other Transvalor software to simulate the entire manufacturing chain; typically FORGE® for open-die forging or rolling of long products and SIMHEAT® for heat treatments of cast parts.
