Developed continuously over the last 40 years, the finite-element groundwater simulator FEFLOW covers key processes that are relevant for the optimisation of near-surface and deep geothermal installations. In addition to the software functionality covering subsurface flow, reactive mass transport and heat transport, FEFLOW offers modules to model special conditions, such as piFreeze for soil freezing/thawing, piChemfor chemical equilibrium systems, and piHMC for hydro mechanical coupling.

在过去40年里,有限元地下水模拟软件FEFLOW不断发展完善,揭示了诸多优化浅层和深层地热装置安装的关键过程。FEFLOW除了能模拟地下水流运动,物质传输和热传递外,还提供给了用户用于特殊场景模拟的模块,例如:piFreeze(冻土)模块用于土壤的冻结和融化过程的模拟,piChem(复杂地化)模块用于化学平衡系统模拟,piHMC用于水力和岩土力学的耦合模拟。

In this interview, Dr. Vincent Badoux, Head of Department, Hydro geology & Geothermics of GEOTEST AG and Board Member of the Swiss Geothermal Association, shares his experience on modelling groundwater and geothermal energy with FEFLOW.

在这次采访中,GEOTEST公司水文地质和地热学部门主管和瑞士地热协会董事会成员,Vincent Badoux博士分享了他在使用FEFLOW进行地下水和地热过程模拟中的经验。



Q: Mr.Badoux, you are a long-standing FEFLOW user and DHI customer. Thanks for taking time to answer our questions today.

Badoux先生,你是FEFLOWDHI的老用户,感谢您今天接受我们的采访。
A:
Gladly. DHI is an important partner for us and it is my pleasure to do this short interview.

谢谢,DHI是我们公司重要的合作伙伴,我非常高兴接受此次对话。


Q: How long has GEOTEST used FEFLOW and why does the software lend itself so well to your operations?

贵公司使用FEFLOW多久了?为什么FEFLOW能够在你们的日常业务中起到重要作用?
A:
GEOTEST has used the FEFLOW software since 2007. Due to its flexibility, versatility,reliability and its compatibility, e.g., with GIS files and other interfaces,the software has proven itself again and again in our everyday work.

GEOTEST公司从2007年开始使用FEFLOW。FEFLOW具有的灵活性,实用性,可靠性和良好的兼容性,比如跟GIS数据和其他软件数据的交互,在我们日常的使用中不断地被证明。


Q: Which   geothermal questions do you answer with FEFLOW?

你们使用FEFLOW解决了哪些地热相关的问题?
A:
We use FEFLOW to address a number of hydrogeological, geotechnical and geothermal questions.In geothermal energy applications, we use FEFLOW most for low-temperature projects, such as thermal groundwater installations or in combination with geothermal heat exchangers and energy piles. All these modelled together with very challenging subsurface conditions. Currently, we are planning a heating and cooling unit for a new warehouse of one of Switzerland's largest online shops. We are also modelling a geothermal system for heating network of thecity of Davos. In another project, we used FEFLOW to understand the feasibility of a cooling system for an ice rink in the city of Bern. We also use FEFLOW to simulate deep geothermal projects – typically in cases where other solutions can no longer support our needs. In a recent project, we helped explore heat generating opportunities in an existing deep bore hole in the Geneva area.

我们使用FEFLOW解决了一系列水文地质、地球化学和地热问题。在地热能利用方面,我们更多地使用FEFLOW进行一些低温项目的研究,比如热源地下水设施的安装或者与地热热量交换器和能量堆的组合,所有的这些建模过程都基于极具挑战性的水文地质条件。目前,我们正在计划为瑞士最大的在线商店之一的新仓库提供加热和冷却装置。我们还在为达沃斯市的供热系统提供地热建模。在另一个项目中,我们运用FEFLOW来论证伯尔尼市的一个溜冰场使用冷却系统的可行性。我们还会在其他的解决方案无法满足我们需求的情况下,用FEFLOW来模拟深层地热项目。在最近的一个项目中,我们帮助探索日内瓦地区现有深孔中的热源。


Q: Which FEFLOW features are the most useful for your work and why?

在你们日常工作中,FEFLOW的哪些功能对你们来说是最有用的,为什么?
A:
Undoubtedly,the 'Reverse Flow Field' option that assists in determining well capture zones.In addition, the ability to develop your own tools with the IFM-Python interface is a great advantage. DHI's plug-ins are also very useful. Without these features, we would not always be able to answer our customers' specific questions.

毫无疑问,“反向流场”选项可以辅助确定井的捕获区。此外,使用IFM-Python界面进行自主开发是FEFLOW很大的一个优势。DHI的插件也非常有用。没有这些功能,我们将无法回答客户的特定问题。


Q: What makes FEFLOW special for you?

FEFLOW有什么令你感到印象深刻的?
A:
It is important for us that universities use FEFLOW because their graduates are new comers to the workforce, who have initial exposure to the simulator. Equally valuable, however, are THE ACADEMY by DHI's training opportunities because continuous training of our existing employees is one of our top priorities. FEFLOW is a professional standard in the industry and it provides us and our customers a certain degree of security.

对我们而言,一些大学使用FEEFLOW来进行教学这一点非常重要,因为一些拥有初级建模经验的毕业生最终会加入我们。另外,DHI的培训机会同样有价值,因为对我们现有员工的持续培训是我们的首要任务之一。FEFLOW是行业中的专业标准,可为我们和我们的客户提供某种程度的保障。


Q: What practical tips would you like to give other FEFLOW users?

你对其他FEFLOW用户有什么建议?
A:
We would recommend THE ACADEMY's training opportunities to everyone and not to hesitate to contact and benefit from FEFLOW Support. In addition to DHI's professional competence, we particularly appreciate their kindness and helpfulness. We also recommend all FEFLOW users to stay up-to-date with the software. In this way, we too benefit from the latest functionalities.   

我们会向所有人推荐DHI的培训机会,并且毫不犹豫地与FEFLOW支持小组进行联系并从中受益。除了DHI的专业能力外,我们特别感谢他们的友善帮助。我们还建议所有FEFLOW用户持续跟进软件的最新功能,这样,我们也可以从最新功能中受益。
