Mandeep Singh Product Manager- CAESAR II Indian Mission on Mars
As India’s maiden mission to Mars, the Mangalyaan, arrived in orbit, Indians all over the world (including me) celebrated with pride. The Indian Space Research Organization’s (ISRO) mission took only three years and cost a mere $74 million.
The mission got me to thinking about living on mars and the feasibility of establishing a colony there. What would we use as our source of power? Would nuclear energy work? After all, it was successfully used on NASA’s Curiosity Mars rover mission.
Some other factors to consider:
1. Temperatures on Mars vary a lot during the day and from the equator to the poles. This means any structures we build would have to withstand severe thermal fatigue cycles. 2. The atmospheric pressure on Mars is 100 times less than that on the Earth. An artificial atmosphere with regulated temperatures and pressures would have to be created. 3. Gravity on Mars is about 30% of that on the Earth. That means, we would need a fewer number of supports for piping in our plants!
For us, living on Mars won’t be a reality for a while. "In the meantime," adds Dr Richard Zurek, Chief Scientist in the Mars Program Office at NASA’s Jet Propulsion Laboratory (JPL), "we should take care of our own planet. It’s always nice to have good home base."*So, you can use Intergraph’s CAESAR II for your pipe stress work on Earth and on Mars (you just have to be able to define the conditions).
Over the years we have produced webinars on variety of topics. These webinars are hosted on our website and blog and are available for any user to download and view. When we hire new developers, they watch some of these webinars as part of their training. It’s a great resource for you too!
If you have thermal expansion load case that fails, how do you solve it and what would you try first? 1. Remove or modify supports 2. Include flexibility of vessel/tank nozzle 3. Include flexibility of structure supporting the piping 4. Select a “better” fitting with smaller SIF 5. Use finite element analysis to compute more accurate SIFs for Tees* 6. Use finite element analysis to flexibilities for Tees*
*There is an easy way to accomplish items 5 and 6, using FEATools.

While modeling your piping system in CAESAR II, have you ever asked yourself what is around your piping, or where you might be able to locate a support or add an expansion loop or check clearances? Well, in CAESAR II, you can to import the whole CAD models as a visual reference and overlay on top of your CAESAR II model. In the CAESAR II Piping Input, use the Reference CAD Models Toolbar to import either CADWorx (*.dwg) or Smart 3D/SPR (*.vue) models.
